All, I'm happy to go with whatever the WG wants on this.  As Dan is 
aware, there is work associated with doing a Mime type - the 
following, from the TAG finding on Mime types 
(, makes it clear what we 
would need to do.  Since it needs to be done no later than CR, which 
we hope to reach by December or Jan, we need to reach consensus and

1. Registration of Media Types by W3C Working Groups

W3C Working Groups engaged in defining a language SHOULD arrange for 
the registration of an Internet Media Type (defined in RFC 2046 
[RFC2046]) for that language; see [IANAREG] for registration 
instructions. The IETF registration forms MUST be available for 
review along with the specification no later than Candidate 
Recommendation (or at last call if the Working Group expects to 
advance directly to Proposed Recommendation). The IETF registration 
forms SHOULD be available for review no later than last call.

The conventions and framework established by RFC 3023 [RFC3023] 
SHOULD be followed when registering an Internet Media Type for a 
language that uses XML syntax.
