Hi Dave,

Here's one approach:

At the beginning of your XSL, make a key for @id attributes in the document.

Then for each @refid in the document, check if there is a matched key.
 If it doesn't report an error.

(Schematron is one way you could check this quickly... But if you want
a lighter weight XSLT, it should be simple to do.)
