This is a comment against the XBL2 last call WD.

I believe the spec needs a media type, if only because the TAG
recommends it[1].  That finding links to a document[2] which describes
two possible registration procedures.  I suggest the group follow the
"new procedure" because it avoids duplication of normative text
between multiple specifications (the XBL spec & a would-be
registration RFC) and independent standards organizations (W3C and
IETF).

Attached is a template you can start with, which assumes the new procedure.

Cheers,

Appendix A

  Type name: application

  Subtype name: xbl+xml

  Required parameters: none

  Optional parameters:

      charset
          This parameter has identical semantics to the charset parameter
          of the "application/xml" media type as specified in [XMLMIME].

  Encoding considerations:

      By virtue of XBL content being XML, it has the same considerations
      when sent as 'application/xbl+xml' as does XML.  See [XMLMIME],
      section 3.2.

  Security considerations:

      See section 1.3 of this specification.

      In addition, because XBL is XML, the security considerations for XML
      itself apply; see [XMLMIME] section 10.

  Interoperability considerations:

      There are no known interoperability considerations beyond those for XML
      itself.  See section 3.1 of [XMLMIME].

  Published specification:

      This document.

  Applications which use this media type:

      None at this point in time.

  Additional information:

      Magic number: none
      File extensions: xbl2
      Macintosh File Type code: TEXT
      Fragment identifiers: @@@ I'm not sure - sec 3.4 doesn't seem
to cover that case

  Person & email address to contact for further information:

  Intended usage: COMMON

  Author/Change controller:

    The XBL specification is a work product of the World Wide Web
    Consortium's Web Application Formats Working Group.  The W3C
    has change control over this specification.
