Checking if an extension function exists and implementation/version sniffing

Hi,

My test framework (http://xformsunit.org/) is trying hard to work with
several XForms implementations using generic/standard XForms features
but I get a number of interoperability issues and I would need to test
if extension functions are available in the implementation that's
running a form (or a test suite) and/or to identify the implementation.

The mechanism to do so in XForms 1.1
(http://www.w3.org/TR/xforms11/#expr-lib-extension ) seems to be rather
"destructive" as it would stop any processing when a function is not
available.

Do you have any idea on how I can achieve this kind of things?

Thanks,

Eric
