I think this will require musicbrainz-specific code, and I'm not going to add 
that to feedparser. All is not lost, however: when I have time it's my 
intention to make it easier for developers to add their own custom namespace 
support.

I don't think it's musicbrainz specific, it's just parsing elements with one 
namespace within elements of another namespace.
