You were trying to say my use of XPath/XQuery in unit tests was bad,
and to use Schematron instead:

"There is a ready made fix for this problem - write your assertions
with a tool that doesn't force you to expose your xpaths - Schematron.
This last point has been pretty much universally accepted and widely
known in the QA community since the turn of the millenium."

I can't help but smile reading that last sentence again - you could
call that a failed assertion.
