"OAuth" not listed in initial authentication scheme registry

In 
http://tools.ietf.org/html/draft-ietf-httpbis-authscheme-registrations-04 <http://tools.ietf.org/html/draft-ietf-httpbis-authscheme-registrations-03>

I note that the OAuth authentication scheme is not listed. "OAuth" is 
defined in RFC 5849, section 3.5.1.

See http://tools.ietf.org/html/rfc5849#section-3.5.1 for a full 
description of the authentication scheme.
