That would be great! :-)
For parsing those elements I recommend looking at 
"xmlSchemaParseSimpleType" in xmlschemas.c; there you'll find an example 
  of how to use the new error functions, and of validation of attributes 
and their values.

The main issues I see here:
1. how to restrict the XPath expressions as imposed by the spec
2. just keep in mind that the XPath execution should be able to work on 
a stream someday (as mentioned by Daniel)

You might consider using the XML IRC channel for discussion as well 
(http://www.xmlsoft.org/bugs.html).

I'm currently trying to get along with Python to integrate the W3C 
schema test suite.
