[xsl] Slightly OT: Formal XSD schema datatype for xpointers?

[Eliot Kimber <ekimber@xxxxxxxxxxxxxxxxxxx>]

I'm asking here because this is currently the main XML-related list I 
follow and I'm pretty sure that the folks here will know the answer.

I'm declaring a new XSD schema for my own use and am declaring the 
XInclude href and xpointer attributes [I feel that that design is the 
best general design for addresses of XML resources so I use it for 
everything that has the semantic of referencing XML elements--and no, I 
don't use XLink for this: short answer: XLink is not appropriate for 
authoring].

I would like to declare the xpointer attribute with a datatype that 
actually reflects the basic syntax rules for XPointers and I sort of 
expected to find a datatype like that defined somewhere in the W3C world 
of specifications but I couldn't find it.

Does such a datatype exist in a normative or non-normative W3C 
publication? I suspect the answer is no but I just wanted to make sure.

Thanks,

Eliot
