The comments in Schema Structures, Section 4.2.1, regarding the use of
xpointer to identify schema components do not go quite far enough to
permit broad reuse of important features defined by XML Schema.

Specifically, after lengthy discussion and deliberation the RDF Schema WG
was persuaded to defer all base datatyping specifications until after an
XML Schema specification was completed so as to be able to leverage any
base datatypes from XML.

It will be a significant benefit to the wider XML application community
if canonical URIs were defined for each of the built-in datatypes as well
as for each the specified facets.

This request is certainly a subset of the broader request for an
algorithm to derive a full URI for every Schema component from the
namespace URI and the local name (and, perhaps the type or symbol
space).  I want to emphasize that even if the general case remains
unaddressed in version 1, it is important and useful to address the
specific case of the built-in datatypes.  This partially addresses
bullet 3.9 of http://www.w3.org/TR/1999/NOTE-schema-arch-19991007
