Maybe your idea will work for the XInclude part, though I think it's likely to 
be messy either way.  However wording that says "xpath() processors must 
report an error if they encounter either an unresolved entity" is not really 
meaningful.  You rightly couch your draft mostly by reference to XPath, and 
XPath has no concept of an XML entity (besides the sliver in 
unparsed-entity-uri().  I think it's not really meaningful, then to say that 
an XPath processor could encounter an unresolved entity.
