They ought to be rejected. Please understand that these namespace names are sent only as the value of 'xmlns' in XMPP streams. They are not in general use anywhere else. XMPP software implementations know what to do with them (and I really doubt that they pass these strings to URI parsers anyway). This is basically a whitelist of known strings and they are not treated as URIs anywhere in the XMPP ecosystem.
