[jdom-interest] Special XMLOutputter which omits namespaces?

[Jason Hunter]

Hi Guillaume,

No, there's no support for that output feature in XMLOutputter.  You're 
basically wanting to output XML with a different semantic meaning than 
it really has in memory, so naturally that's something we didn't include 
and aren't likely to.

We also aren't likely to make the method protected either because 
protected methods are part of the public API so were we to do that, we'd 
have to keep the method always in the future in order to maintain 
backward compatibility.  We don't want to promise anyone that the 
outputter internals will always behave the same way.  Since the code is 
open, you can easily enough solve your problem without requiring the API 
to keep the exact same internal implementation.
