Björn, your conclusion does not follow from your evidence. 

If you see foo/bar+xml, the +xml convention licenses you to assert that this is definitely XML.

If you see foo/bar, the +xml convention does not license you to conclude that it is *not* XML.

The media types that you mention, which are sometimes xml and sometimes not, are thus correctly labelled.
