I don't speak XPath, so as I said earlier, I'm not the one to ask. Conceptually
that would be the right track, but...

Then by all means do not use XPath. But if you use an ID, you don't need to use
an xpointer, just set the Reference URI to "#foo" where foo is the ID. No extra
transform needed, apart from c14n or something else like that.

You can log it somehow, I believe.
