I actually tried that, but this didn't work.
Btw, it is not that simple. It needs to convert also several other tags,
and some are in the middle of the tests.
So, even if this would work, a change like that will introduce lots
of "noise" at the docs.
The approach of adding support for c:namespace: at cdomain
(see the patchset I sent today) is a lot more cleaner.
Thanks,
Mauro
