I've been discussing the collation of nodes from different
documents with (one of?) the author(s) of Sablotron, which
doesn't address this issue properly yet. (If you're reading
this Tom, I hope you don't mind me raising this here)

He raised the following question:
 
 Consider the following 3 files. The
 input file for the genid-question.xsl stylesheet is irrelevant.
 
 <!-- genid-question.xsl -->
 <xsl:transform xmlns:xsl='http://www.w3.org/1999/XSL/Transform'    
 version='1.0'>
 <xsl:template match='/'>
 <xsl:value-of select="generate-id(document('genid1.xml')/a/b) =
     generate-id(document('genid2.xml')/b)"/>
 </xsl:template>
 </xsl:transform>
 
 <!-- genid1.xml -->
 <!DOCTYPE a [ <!ENTITY genid2 SYSTEM "genid2.xml"> ]>
 <a> &genid2; </a>
 
 <!-- genid2.xml -->
 <b/>
 
 Shouldn't this output true? I think it should, but neither XT nor Saxon
 do.

The spec doesn't seem to address this question explicitly.
Does anybody have an answer?
