This document has been superceded.
The design described in previous versions of this document has been
factored into a basic framework (http://www.w3.org/TR/xptr-framework/) which defines XPointer schemes and simple "barename" fragment identifiers, and three additional schemes: http://www.w3.org/TR/xptr-element/, for addressing elements by their position in the document tree,
http://www.w3.org/TR/xptr-xmlns/, for binding namespace
prefixes to namespace name and
http://www.w3.org/TR/xptr-xpointer/, for full
XPath-based addressing.
For information about the requirements that informed development of
this specification,
see http://www.w3.org/TR/NOTE-xptr-req.
