It would be acceptable as a warning. Applications such as Foswiki make a good use, including namespace. Example: <meta name="foswiki.PUBURL" content="http://wiki.abc/pub" /> 85541 1 jukka.k.korpela 2013-04-04 08:09:49 +0000 By HTML5 drafts, unregistered meta keyword is an error. So this bug should be closed as invalid. The issue whether it SHOULD be an error belongs to the discussion about the specs, not to a validator bug list. 86421 2 mike 2013-04-20 14:18:17 +0000 (In reply to comment #1) > By HTML5 drafts, unregistered meta keyword is an error.
