     That is a good point. Does anyone know, does XPath2 
    provide any extra features
    that would be useful for IDREFs?   (I believe that XPath 
    and XSLT have 
    such bad
    support for IDREFs because they expected XLink complex 
    links to take over.)

xslt 2 has full regex support. That should sort out string
splitting.
