+	 * "constraint2", "constraint3"] has the interpretation: "the value of this
+	 * property must meet at least one of constraint1, constraint2 or constraint3".
+	 *
+	 * Reporting of value constraints is optional. An implementation may return
+	 * null, indicating that value constraint information is unavailable (though
+	 * a constraint may still exist).
+	 *
+	 * Returning an empty array, on the other hand, indicates that value constraint
+	 * information is available and that no constraints are placed on this value.
+	 *
+	 * In the case of multi-value properties, the constraint string array returned
+	 * applies to all the values of the property.
+	 *
+	 * The constraint strings themselves having differing formats and
+	 * interpretations depending on the type of the property in question. The
+	 * following describes the value constraint syntax for each property type:
+	 *
+	 * STRING and URI: The constraint string is a regular expression pattern. For
+	 * example the regular expression ".*" means "any string, including the empty
+	 * string". Whereas a simple literal string (without any RE-specific meta-
+	 * characters) like "banana" matches only the string "banana".
+	 *
+	 * PATH: The constraint string is a JCR path with an optional "*" character
+	 * after the last "/" character. For example, possible constraint strings for
+	 * a property of type PATH include:
+	 *  "/myapp:products/myapp:televisions"
+	 *  "/myapp:products/myapp:televisions/"
+	 *  "/myapp:products/*"
+	 *  "myapp:products/myapp:televisions"
+	 *  "../myapp:televisions"
+	 *  "../myapp:televisions/*"
+	 *
+	 * 	 * The following principles apply:
+	 *  The "*" means "matches descendants" not "matches any subsequent path".
+	 *  For example, /a/* does not match /a/../c. The constraint must match the
+	 *  normalized path.
+	 *  Relative path constraint only match relative path values and absolute
+	 *  path constraints only match absolute path values.
+	 *  A trailing "/" has no effect (hence, 1 and 2, above, are equivalent).
+	 *  The trailing "*" character means that the value of the PATH property is
+	 *  restricted to the indicated subgraph (in other words any additional
+	 *  relative path can replace the "*"). For example, 3, above would allow
+	 *  /myapp:products/myapp:radios, /myapp:products/myapp:microwaves/X900,
+	 *  and so forth.
+	 *  A constraint without a "*" means that the PATH property is restricted
+	 *  to that precise path. For example, 1, above, would allow only the
+	 *  value /myapp:products/myapp:televisions.
+	 *  The constraint can indicate either a relative path or an absolute path
+	 *  depending on whether it includes a leading "/" character. 1 and 4,
+	 *  above for example, are distinct.
+	 *  The string returned must reflect the namespace mapping in the current
+	 *  Session (i.e., the current state of the namespace registry overlaid
+	 *  with any session-specific mappings). Constraint strings for PATH
+	 *  properties should be stored in fully-qualified form (using the actual
+	 *  URI instead of the prefix) and then be converted to prefix form
+	 *  according to the current mapping upon the
+	 *  PropertyDefinition.getValueConstraints call.
+	 *
+	 * NAME: The constraint string is a JCR name in prefix form. For example
+	 * "myapp:products". No wildcards or other pattern matching are supported.
+	 * As with PATH properties, the string returned must reflect the namespace
+	 * mapping in the current Session. Constraint strings for NAME properties
+	 * should be stored in fully-qualified form (using the actual URI instead of
+	 * the prefix) and then be converted to prefix form according to the current
+	 * mapping.
+	 *
+	 * REFERENCE and WEAKREFERENCE: The constraint string is a JCR name in prefix
+	 * form. This name is interpreted as a node type name and the REFERENCE or
+	 * WEAKREFERENCE property is restricted to referring only to nodes that have
+	 * at least the indicated node type. For example, a constraint of "mytype:document"
+	 * would indicate that the property in question can only refer to nodes that
+	 * have at least the node type mytype:document (assuming this was the only
+	 * constraint returned in the array, recall that the array of constraints are
+	 * to be ORed together). No wildcards or other pattern matching are supported.
+	 * As with PATH properties, the string returned must reflect the namespace
+	 * mapping in the current Session. Constraint strings for REFERENCE and
+	 * WEAKREFERENCE properties should be stored by the implementation in
+	 * fully-qualified form (using the actual URI instead of the prefix) and then
+	 * be converted to prefix form according to the current mapping.
+	 *
+	 * BOOLEAN: BOOLEAN properties will always report a value constraint
+	 * consisting of an empty array (meaning no constraint). In implementations
+	 * that support node type registration any value constraint set on BOOLEAN is
+	 * ignored and discarded.
+	 *
+	 * The remaining types all have value constraints in the form of inclusive
+	 * or exclusive ranges: i.e., "[min, max]", "(min, max)", "(min, max]" or
+	 * "[min, max)". Where "[" and "]" indicate "inclusive", while "(" and ")"
+	 * indicate "exclusive". A missing min or max value indicates no bound in
+	 * that direction. For example [,5] means no minimum but a maximum of 5
+	 * (inclusive) while [,] means simply that any value will suffice, The meaning
+	 * of the min and max values themselves differ between types as follows:
+	 *
+	 * BINARY: min and max specify the allowed size range of the binary value in bytes.
+	 * DATE: min and max are dates specifying the allowed date range. The date
+	 * strings must be in the ISO8601-compliant format: YYYY-MM-DDThh:mm:ss.sssTZD.
+	 * LONG, DOUBLE: min and max are numbers.
+	 *

+	 * that a DATE, LONG or DOUBLE is constrained to be equal to some disjunctive
+	 * set of constants, a string consisting of just the constant itself, "c" may

+	 * registration, the value returned by PropertyDefinition.getValueConstraints()
+	 * will always use the standard notation.
+	 *
+	 * Because constraints are returned as an array of disjunctive constraints,
+	 * in many cases the elements of the array can serve directly as a "choice list".
+	 * This may, for example, be used by an application to display options to

+	 * urrent Session as well as the restrictions specified by the parameters of
+	 * this method. These restrictions are stated in terms of characteristics of the
+	 * associated parent node of the event.
+	 *
+	 * The associated parent node of an event is the parent node of the item at (or
+	 * formerly at) the path returned by Event.getPath(). The following restrictions
+	 * are available:
+	 *  absPath, isDeep: Only events whose associated parent node is at absPath (or
+	 *   within its subgraph, if isDeep is true) will be received. It is permissible
+	 *   to register a listener for a path where no node currently exists.
+	 *  uuid: Only events whose associated parent node has one of the identifiers in
+	 *   this list will be received. If his parameter is null then no identifier-
+	 *   related restriction is placed on events received. Note that specifying an
+	 *   empty array instead of null would result in no nodes being listened to. The
+	 *   term "UUID" is used for compatibility with JCR 1.0.
+	 *  nodeTypeName: Only events whose associated parent node has one of the node
+	 *   types (or a subtype of one of the node types) in this list will be received.
+	 *   If his parameter is null then no node type-related restriction is placed on
+	 *   events received. Note that specifying an empty array instead of null would
+	 *   result in no nodes types being listened to.
+	 * The restrictions are "ANDed" together. In other words, for a particular node
+	 * to be "listened to" it must meet all the restrictions.
+	 * Additionally, if noLocal is true, then events generated by the session
+	 * through which the listener was registered are ignored. Otherwise, they are
+	 * not ignored.
+	 *
+	 * The filters of an already-registered EventListener can be changed at runtime
+	 * by re-registering the same EventListener object (i.e. the same actual object)
+	 * with a new set of filter arguments. The implementation must ensure that no
+	 * events are lost during the changeover.
+	 *
+	 * In addition to the filters placed on a listener above, the scope of
+	 * observation support, in terms of which subgraphs are observable, may also be
+	 * subject to implementation-specific restrictions. For example, in some
+	 * repositories observation of changes in the jcr:system subgraph may not be

+ * The BOOLEAN property type is used to store boolean values.
+ * A NAME is a pairing of a namespace and a local name. When read, the namespace is mapped to the current prefix. See 4.2.6.2 Name in the specification.
+ * A PATH property is an ordered list of path elements. A path element is a NAME with an optional index. When read, the NAMEs within the path are mapped to their current prefix. A path may be absolute or relative. See 4.2.6.3 Path in the specification.
+ * A REFERENCE property stores the identifier of a referenceable node (one having type mix:referenceable), which must exist within the same workspace or session as the REFERENCE property. A REFERENCE property enforces this referential integrity by preventing (in level 2 implementations) the removal of its target node. See 4.2.6.4 Reference in the specification.
+ * A WEAKREFERENCE property stores the identifier of a referenceable node (one having type mix:referenceable). A WEAKREFERENCE property does not enforce referential integrity. See 4.2.6.5 Weak Reference in the specification.
+ * A URI property is identical to STRING property except that it only accepts values that conform to the syntax of a URI-reference as defined in RFC 3986. See also 4.2.6.6 URI in the specification.
+ * UNDEFINED can be used within a property definition (see 4.7.5 Property Definitions) to specify that the property in question may be of any type. However, it cannot be the actual type of any property instance. For example it will never be returned by Property.getType() and (in level 2 implementations) it cannot be assigned as the type when creating a new property.

+ * Performs a full-text search.
+ *
+ * The full-text search expression is evaluated against the set of full-text
+ * indexed properties within the full-text search scope. If property is
+ * specified, the full-text search scope is the property of that name on the
+ * selector node in the node-tuple; otherwise the full-text search scope is all
+ * properties of the selector node (or, in some implementations, all properties
+ * in the node subgraph).
+ *
+ * Which properties (if any) in a repository are full-text indexed is
+ * implementation determined.
+ *
+ * It is also implementation determined whether fullTextSearchExpression is
+ * independently evaluated against each full-text indexed property in the
+ * full-text search scope, or collectively evaluated against the set of such
+ * properties using some implementation-determined mechanism.
+ *
+ * Similarly, for multi-valued properties, it is implementation determined
+ * whether fullTextSearchExpression is independently evaluated against each
+ * element in the array of values, or collectively evaluated against the array
+ * of values using some implementation-determined mechanism.
+ *
+ * At minimum, an implementation must support the following
+ * fullTextSearchExpression grammar:
+ *
+ *  fullTextSearchExpression ::= [-]term {whitespace [OR] whitespace [-]term}
+ *  term ::= word | '"' word {whitespace word} '"'
+ *  word ::= (A string containing no whitespace)

+/**
+ * A query in the JCR query object model.
+ *
+ * The JCR query object model describes the queries that can be evaluated by a JCR
+ * repository independent of any particular query language, such as SQL.
+ *
+ * A query consists of:
+ *
+ * * a source. When the query is evaluated, the source evaluates its selectors and
+ *   the joins between them to produce a (possibly empty) set of node-tuples. This
+ *   is a set of 1-tuples if the query has one selector (and therefore no joins), a
+ *   set of 2-tuples if the query has two selectors (and therefore one join), a set
+ *   of 3-tuples if the query has three selectors (two joins), and so forth.
+ * * an optional constraint. When the query is evaluated, the constraint filters the
+ *   set of node-tuples.
+ * * a list of zero or more orderings. The orderings specify the order in which the
+ *   node-tuples appear in the query results. The relative order of two node-tuples
+ *   is determined by evaluating the specified orderings, in list order, until
+ *   encountering an ordering for which one node-tuple precedes the other. If no
+ *   orderings are specified, or if for none of the specified orderings does one
+ *   node-tuple precede the other, then the relative order of the node-tuples is
+ *   implementation determined (and may be arbitrary).
+ * * a list of zero or more columns to include in the tabular view of the query
+ *   results. If no columns are specified, the columns available in the tabular view
+ *   are implementation determined, but minimally include, for each selector, a column
+ *   for each single-valued non-residual property of the selector's node type.
+ *
+ * The query object model representation of a query is created by factory methods in the QueryObjectModelFactory.

+	 * The incoming XML is deserialized into a subgraph of items immediately below
+	 * the node at parentAbsPath.
+	 *
+	 * This method simply returns the ContentHandler without altering the state of
+	 * the session; the actual deserialization to the session transient space is
+	 * done through the methods of the ContentHandler. Invalid XML data will
+	 * cause the ContentHandler to throw a SAXException.
+	 *
+	 * As SAX events are fed into the ContentHandler, the tree of new items is built
+	 * in the transient storage of the session. In order to dispatch the new
+	 * content, save must be called. See Workspace.getImportContentHandler() for
+	 * a workspace-write version of this method.
+	 *
+	 * The flag uuidBehavior governs how the identifiers of incoming nodes are
+	 * handled. There are four options:
+	 *
+	 * ImportUUIDBehavior.IMPORT_UUID_CREATE_NEW: Incoming identifiers nodes are added
+	 * in the same way that new node is added with Node.addNode. That is, they are either
+	 * assigned newly created identifiers upon addition or upon save (depending on the
+	 * implementation). In either case, identifier collisions will not occur.
+	 *
+	 * ImportUUIDBehavior.IMPORT_UUID_COLLISION_REMOVE_EXISTING: If an incoming node has
+	 * the same identifier as a node already existing in the workspace then the already
+	 * existing node (and its subgraph) is removed from wherever it may be in the workspace
+	 * before the incoming node is added. Note that this can result in nodes "disappearing"
+	 * from locations in the workspace that are remote from the location to which the
+	 * incoming subgraph is being written. Both the removal and the new addition will be
+	 * persisted on save.
+	 *
+	 * ImportUUIDBehavior.IMPORT_UUID_COLLISION_REPLACE_EXISTING: If an incoming node has
+	 * the same identifier as a node already existing in the workspace, then the
+	 * already-existing node is replaced by the incoming node in the same position as the
+	 * existing node. Note that this may result in the incoming subgraph being disaggregated
+	 * and "spread around" to different locations in the workspace. In the most extreme
+	 * case this behavior may result in no node at all being added as child of parentAbsPath.
+	 * This will occur if the topmost element of the incoming XML has the same identifier as
+	 * an existing node elsewhere in the workspace. The change will be persisted on save.
+	 *
+	 * ImportUUIDBehavior.IMPORT_UUID_COLLISION_THROW: If an incoming node has the same
+	 * identifier as a node already existing in the workspace then a SAXException is thrown
+	 * by the ContentHandler during deserialization.
+	 *
+	 * Unlike Workspace.getImportContentHandler, this method does not necessarily enforce
+	 * all node type constraints during deserialization. Those that would be immediately
+	 * enforced in a session-write method (Node.addNode, Node.setProperty etc.) of this
+	 * implementation cause the returned ContentHandler to throw an immediate SAXException
+	 * during deserialization. All other constraints are checked on save, just as they are
+	 * in normal write operations. However, which node type constraints are enforced depends
+	 * upon whether node type information in the imported data is respected, and this is an
+	 * implementation-specific issue.
+	 *
+	 * A SAXException will also be thrown by the returned ContentHandler during deserialization
+	 * if uuidBehavior is set to IMPORT_UUID_COLLISION_REMOVE_EXISTING and an incoming node has
+	 * the same identifier as the node at parentAbsPath or one of its ancestors.

+	 * Deserializes an XML document and adds the resulting item subgraph as a
+	 * child of the node at $parentAbsPath.
+	 * If the incoming XML does not appear to be a JCR system view XML document
+	 * then it is interpreted as a document view XML document.
+	 *
+	 * The tree of new items is built in the transient storage of the Session. In order
+	 * to persist the new content, save must be called. The advantage of this
+	 * through-the-session method is that (depending on what constraint checks the
+	 * implementation leaves until save) structures that violate node type constraints
+	 * can be imported, fixed and then saved. The disadvantage is that a large import
+	 * will result in a large cache of pending nodes in the session. See
+	 * Workspace.importXML(string, string, integer) for a version
+	 * of this method that does not go through the Session.
+	 *
+	 * The flag $uuidBehavior governs how the identifiers of incoming nodes are
+	 * handled. There are four options:
+	 *
+	 * ImportUUIDBehavior.IMPORT_UUID_CREATE_NEW: Incoming nodes are added in the same
+	 * way that new node is added with Node.addNode. That is, they are either assigned
+	 * newly created identifiers upon addition or upon save (depending on the implementation,
+	 * see 4.9.1.1 When Identifiers are Assigned in the specification). In either case,
+	 * identifier collisions will not occur.
+	 * ImportUUIDBehavior.IMPORT_UUID_COLLISION_REMOVE_EXISTING: If an incoming node has
+	 * the same identifier as a node already existing in the workspace then the already
+	 * existing node (and its subgraph) is removed from wherever it may be in the workspace
+	 * before the incoming node is added. Note that this can result in nodes "disappearing"
+	 * from locations in the workspace that are remote from the location to which the
+	 * incoming subgraph is being written. Both the removal and the new addition will be
+	 * dispatched on save.
+	 * ImportUUIDBehavior.IMPORT_UUID_COLLISION_REPLACE_EXISTING: If an incoming node
+	 * has the same identifier as a node already existing in the workspace, then the
+	 * already-existing node is replaced by the incoming node in the same position as
+	 * the existing node. Note that this may result in the incoming subgraph being
+	 * disaggregated and "spread around" to different locations in the workspace. In the
+	 * most extreme case this behavior may result in no node at all being added as child
+	 * of parentAbsPath. This will occur if the topmost element of the incoming XML has
+	 * the same identifier as an existing node elsewhere in the workspace. The change
+	 * will be dispatched on save.
+	 * ImportUUIDBehavior.IMPORT_UUID_COLLISION_THROW: If an incoming node has the same
+	 * identifier as a node already existing in the workspace then an
+	 * ItemExistsException is thrown.
+	 * Unlike Workspace.importXML(string, string, integer), this method does not
+	 * necessarily enforce all node type constraints during deserialization.
+	 * Those that would be immediately enforced in a normal write method (Node.addNode,
+	 * Node.setProperty etc.) of this implementation cause an immediate
+	 * ConstraintViolationException during deserialization. All other constraints are
+	 * checked on save, just as they are in normal write operations. However, which node
+	 * type constraints are enforced depends upon whether node type information in the
+	 * imported data is respected, and this is an implementation-specific issue.
+	 *
+	 * @param string $parentAbsPath the absolute path of the node below which the deserialized subgraph is added.
+	 * @param string $in An URI from which the XML to be deserialized is read.
+	 * @param integer $uuidBehavior a four-value flag that governs how incoming identifiers are handled.
+	 * @return void
+	 * @throws RuntimeException if an error during an I/O operation occurs.
+	 * @throws PHPCR_PathNotFoundException if no node exists at parentAbsPath and this implementation performs this validation immediately.
+	 * @throws PHPCR_ItemExistsException if deserialization would overwrite an existing item and this implementation performs this validation immediately.
+	 * @throws PHPCR_ConstraintViolationException if a node type or other implementation-specific constraint is violated that would be checked on a session write method or if uuidBehavior is set to IMPORT_UUID_COLLISION_REMOVE_EXISTING and an incoming node has the same UUID as the node at parentAbsPath or one of its ancestors.
+	 * @throws PHPCR_Version_VersionException if the node at $parentAbsPath is read-only due to a checked-in node and this implementation performs this validation immediately.
+	 * @throws PHPCR_InvalidSerializedDataException if incoming stream is not a valid XML document.
+	 * @throws PHPCR_Lock_LockException if a lock prevents the addition of the subgraph and this implementation performs this validation immediately.

+	 * in the indicated other workspace and a "merge test result" is determined

+	 *    in terms of version history).

+	 * test, of the base version of the corresponding node that caused the merge
+	 * failure. This record is kept in the jcr:mergeFailed property of this node.
+	 * After a merge, this property will contain one or more (if multiple merges
+	 * have been performed) REFERENCEs that point to the "offending versions".

+	 * passing the version object referred to be the jcr:mergeFailed property
+	 * that the client wishes to connect to this node in the version graph. This

+	 *
+	 * If the client chooses not to connect this node to a particular version
+	 * referenced in the jcr:mergeFailed property, he calls cancelMerge(String, Version).
+	 * This has the effect of removing the reference to the specified version
+	 * from jcr:mergeFailed without adding it to jcr:predecessors.
+	 *
+	 * Once the last reference in jcr:mergeFailed has been either moved to
+	 * jcr:predecessors (with doneMerge) or just removed from jcr:mergeFailed
+	 * (with cancelMerge) the jcr:mergeFailed property is automatically removed,
+	 * thus enabling this node to be checked-in, creating a new version (note
+	 * that before the jcr:mergeFailed is removed, its OnParentVersion setting of
+	 * ABORT prevents checkin). This new version will have a predecessor

+	 *   child nodes and properties defined by T that are present on M. For
+	 *   example, a node M that is mix:versionable may be copied such that the

+	 * * Each REFERENCE or WEAKEREFERENCE property R in S is copied to its new
