[xsl] function-available() test on stylesheet functions

I was trying to use function-available() to try to determine if a
stylesheet function had been defined.  I eventually figured out that
stylesheet functions are not in the proper context to cause
function-available() to ever be true.

So my question is, is there another way to test to see if a stylesheet
function exists?
