Cleaning up unused namespace declaration

[Stefano Mazzocchi]

I'm not normally bugged by namespace declarations which aren't used, 
but boy, something like this just can't go on without me to do 
something about it:

<br xmlns:dir="http://apache.org/cocoon/directory/2.0"; 
xmlns:include="http://apache.org/cocoon/include/1.0"/>

[taken from my blog output]

do you have any suggestions on how to use the xml serializer so that it 
stops doing that?
