  Hum, so basically currently AxKit does ask for error messages to be
generated and handles whether they should be output or not at it's
own level. That's not what I had in mind when I gave the profiling result.
In that case the internal libxslt function is called but the debug
formatting string is not generated, and should not if AxKit didn't ask
for this formatting to occur.
