XML XPointer Requirements Version 1.0

This document presents requirements for the XPointer language.
XPointer provides ways to directly identify any node, data, or
selection in any XML document by describing its structure and
context. An identified data location is called a "target." The
XPointer specification is particularly meant to enable hyperlinks
to identify any such data, regardless of whether there is (or even
could be) an ID on the target or not. The XPointer specification is
now being developed in the XML-Linking Working Group, building on
Working Drafts developed in the XML Working Group.Because the XPointer language must refer to structural parts of
XML documents, those structures must be explicit. Document
structure specifications such as DOM and the XML Information Set
may wish to consider the XPointer requirements in order to insure
interoperability when used with XPointer and XLink.
