Is there a test file for DocBook 5 that has all of the features being tested?

Hello folks,

I am taking Dan McCreary's docbook2xhtml XQuery function module and am incorporating it into a documentation app for eXist.  Is there a DocBook 5 file out there that tests all of the paths in DocBook 5?  If so, then could someone point it out to me?

Thank you,
Loren
