The "XPath files" stylesheets for schemas assume the UBL NDR (only 
global declarations and references, no anonymous types).  The code 
does not work for arbitrary schemas.  The stylesheets create an XML 
instance describing all of the possible XPath addresses to elements 
and attributes possible when using a schema.  Recursive references 
are noted but not traversed.

I'll be interested in looking at XML Zebra for a way of generating 
the XPath instances for UBL schemas, and then I can just use it for 
arbitrary schemas.

The stylesheets for producing the XPath reports from an XPath 
instance are here:

Acknowledging the size of the UBL schemas, a more manageable (but 
more fragile) set of XPaths can be created from an instance.  The 
stylesheets for creating XPath files for arbitrary instances are here:
