Assuming that $criteria_name doesn't include any regular expression meta
characters.  Unfortunately, XSL doesn't have the Perl equivalent of
quotemeta() built into the library.  Certainly you can write a replace() to do
it and create a quotemeta() function to wrap it, but it would have been nice
to say:

matches(.,concat('^',quotemeta($criteria_name),'$'))
