[jdom-interest] Special XMLOutputter which omits namespaces?

[Guillaume Berche]

Hi Jason,

Thanks for your answer. I understand your position given that my need is
pretty specific. Would making the method package-protected (so overrideable
but not exposed publicly) a reasonnable alternative to your concern about
making it protected?

Cheers,

Guillaume.
