+ See http://www.w3.org/XML/1998/namespace.html and
+ http://www.w3.org/TR/REC-xml for information about this namespace.
+
+ This schema document describes the XML namespace, in a form
+ suitable for import by other schema documents.
+
+ Note that local names in this namespace are intended to be defined
+ only by the World Wide Web Consortium or its subgroups. The
+ following names are currently defined in this namespace and should
+ not be used with conflicting semantics by any Working Group,
+ specification, or document instance:
+
+ base (as an attribute name): denotes an attribute whose value
+ provides a URI to be used as the base for interpreting any
+ relative URIs in the scope of the element on which it
+ appears; its value is inherited. This name is reserved
+ by virtue of its definition in the XML Base specification.
+
+ lang (as an attribute name): denotes an attribute whose value
+ is a language code for the natural language of the content of
+ any element; its value is inherited. This name is reserved
+ by virtue of its definition in the XML specification.
+
+ space (as an attribute name): denotes an attribute whose
+ value is a keyword indicating what whitespace processing
+ discipline is intended for the content of the element; its
+ value is inherited. This name is reserved by virtue of its
+ definition in the XML specification.
+
+ Father (in any context at all): denotes Jon Bosak, the chair of
+ the original XML Working Group. This name is reserved by
+ the following decision of the W3C XML Plenary and
+ XML Coordination groups:
+
+ In appreciation for his vision, leadership and dedication
+ the W3C XML Plenary on this 10th day of February, 2000
+ reserves for Jon Bosak in perpetuity the XML name
+ xml:Father
+
+
+
+
+ This schema defines attributes and an attribute group
+ suitable for use by
+ schemas wishing to allow xml:base, xml:lang or xml:space attributes
+ on elements they define.
+
+ To enable this, such a schema must import this schema
+ for the XML namespace, e.g. as follows:
+ <schema . . .>
+ . . .
+ <import namespace="http://www.w3.org/XML/1998/namespace"
+ schemaLocation="http://www.w3.org/2001/03/xml.xsd"/>
+
+ Subsequently, qualified reference to any of the attributes
+ or the group defined below will have the desired effect, e.g.
+
+ <type . . .>
+ . . .
+ <attributeGroup ref="xml:specialAttrs"/>
+
+ will define a type which will schema-validate an instance
+ element with any of those attributes
+
+
+
+ In keeping with the XML Schema WG's standard versioning
+ policy, this schema document will persist at
+ http://www.w3.org/2001/03/xml.xsd.
+ At the date of issue it can also be found at
+ http://www.w3.org/2001/xml.xsd.
+ The schema document at that URI may however change in the future,
+ in order to remain compatible with the latest version of XML Schema
+ itself. In other words, if the XML Schema namespace changes, the version
+ of this document at
+ http://www.w3.org/2001/xml.xsd will change
+ accordingly; the version at
+ http://www.w3.org/2001/03/xml.xsd will not change.
+
+
+
+
+
+ In due course, we should install the relevant ISO 2- and 3-letter
+ codes as the enumerated possible values . . .
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ See http://www.w3.org/TR/xmlbase/ for
+ information about this attribute.
