Hi all, Declaring the default namespace in the document element will only help when you are building the object structure through a builder. But this will not happen if you create the object structure programmatically.
So one option to these kinds of things and to many of the others is to have a global namespace table per model. This is being considered during current OM clean up process. I can remember once Alek proposed something like this long time back.
