Carlos, If I recall correctly, I made that change in order to prevent name spaces from being unnecessarily defined again and again in child elements. Since name space definitions cascade to child elements, that would be excessive clutter.
Apparently, that change needs some fine tuning. Thanks for the report and the example. I believe that I've been able to reproduce the error you have reported. I'll work on it. I'm not sure how hopeful we can be. Seems like I've tried to fix this error several times before. Maybe this time ... Give me a day or two.
