Indeed. :-)

Specifically, according to RFC3305 contemporary view, there is no need
to specify a URN when there are well defined URIs available. They
identify the objects sufficiently. Interestingly also, the set or
registered URN schemes at IANA does not include a W3C namespace, see
http://www.iana.org/assignments/urn-namespaces/urn-namespaces.xml .
It's probably because the W3C has a well defined URI naming scheme.
So, referencing the HTML5 specification and the section therein where
the kind names are defined should be sufficient.
