Ah ha ... that's what I was looking for!  It even seems to be faster 
(at least on my small test doc) than the other approaches.

Thanks!

Just a quick clarification.  Using this new xpath 2 feature, the 
processor will simply look for the first matching example?  So that if 
the cite:* code can be embedded in different schemas, I can do this 
without as performance hit when using the document types preceding it 
in the list?

  <xsl:variable name="citerefs" select="/db:article//@linkend,
                    /db:book//@linkend,
                    /db:chapter//@linkend,
                    //cite:biblioref/@cite:key"/>

For those willing to use XSD ;-)

Most of the schemas I'd be supporting (aside from WordML) are authored 
in RELAX NG.
