Registration of media type application/fdt+xml

Hello,

The FLUTE-revised I-D (http://tools.ietf.org/html/ietf-rmt-flute-revised-14),
currently under IESG review, defines in section 8.2 the application/fdt+xml
Media-Type. Comments on this registration would be greatly appreciated.

Thanks!
Cheers,

   Vincent

---

   Type name: application

   Subtype name: fdt+xml

   Required parameters: none

   Optional parameters: none

   Encoding considerations: The fdt+xml type consists of UTF-8 ASCII
   characters [RFC3629] and must be well-formed XML.

   Additional content and transfer encodings may be used with fdt+xml
   files, with the appropriate encoding for any specific file being
   entirely dependent upon the deployed application.

   Restrictions on usage: Only for usage with FDT Instances which are
   valid according to the XML schema of section 3.4.2.

There should be a rationale for omitting the 'charset' parameter while
also using the "+xml" convention. The idea of the convention is that you
can process all "+xml" "the same", but if some "+xml" types have a char-
set parameter while others do not, applications would handle, say,

  Content-Type: application/fdt+xml;charset=windows-1252

differently, depending on whether they assume it would have a charset
parameter.

This should use the text in RFC 3023 section 7.1 or specify one of the
values in RFC 4288 ('binary', '8bit', etc.)

This seems to be redundant and possibly misleading, considering that
similar registrations do not tend to have such text.

If I understand the various documents, this is where we need to say that
we expect UTF-8. I've kept is as an optional parameter. Is that appropriate?
