There are two issues in here.  As to machine discovery of vocabulary, the
working group has resolved to tighten up the conformance requirement about
discovery.  This will be in the next working draft.

As to priority of role values, the working group agrees that this is important,
but is not part of the Role spec necessarily.  The Role spec does not have
normative behavioral requirements in it, and therefore does not have any
requriement as to how a user agent might interpret the value(s) of the role
attribute.  This is a vocabulary issue, and the working group expects this will
be resolved as part of future vocabulary work either by the XHTML 2 Working
Group or by related activities such as ARIA.
