  Okay, thanks !
I finally took the time to apply your patch (no I hadn't forgotten :-)
it's now in SVN !
Just one thing, it would be nice to add a couple of simple example

have some that would be a good addition.

  Okay, can you provide a separate patch with just the test for the
default namespace, I will apply this too,
