+
+4.2. Same-document References
+
+   A URI reference that does not contain a URI is a reference to the
+   current document.  In other words, an empty URI reference within a
+   document is interpreted as a reference to the start of that document,
+   and a reference containing only a fragment identifier is a reference
+   to the identified fragment of that document.  Traversal of such a
+   reference should not result in an additional retrieval action.
+   However, if the URI reference occurs in a context that is always
+   intended to result in a new request, as in the case of HTML's FORM
+   element, then an empty URI reference represents the base URI of the
+   current document and should be replaced by that URI when transformed
+   into a request.
