I'm glad to be informed, I'm not a member of the "I'm the one who's right"
congregation, to which many programmers seem to belong.

Yes this was fine.

BUT it's useless (isn't it ?). So let's call this a feature request rather
than a bug, even though it ends up with a bug in my situation because the
client parser (a very specialized one, and apparently a pretty bogus one)
does not seem to support empty namespaces.

Thanks very much for this useful link.
