Could XSLTC (which I don't have any experience with yet) be used to

but that probably would still require its execution on a document
instance.
I don't think XSLTC would make any difference since the XSLT processor
cannot know that the XML document has not been modified since the key
was last calculated- only I as the programmer knows that.
I see, you'd need the lookup table resulting from applyint the <xsl:key>
on the document, and that doesn't seem to be available.
Could you use the ID feature built into XML to achieve what you want?
I have looked at it - the problem is that I also use an one-to-many
reverse-id lookup e.g.:
"All elements that refer to the element with this @id"
and I don't think I can cram that into the builtin ID feature.
Can't think of a way to achieve that either. Sounds like you really need
<xsl:key>.
I've never used this, but if all else fails, you might want to take a
look at VTD-XML:
