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 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.
