See RFC 4288 on the possible values for the Encoding considerations. I
am not sure what kind of format you have. Could application/xml also be
used instead of vnd.software602.filler.xml+form, i.e., are these simply
XML documents with a special type, or is there some special encoding
that makes them non-XML without additional decoding? If they are XML,
then I would advise to reference RFC 3023 for encoding considerations,
and add the optional 'charset' parameter, and consider calling the type
e.g. vnd.software602.filler.form+xml.

By the way, your first message in this thread sounded like this is not
the first time you send the proposal, if that is so, please note that I
could not find a previous message from you in the archive.

I would advise against using this extension, I believe it is in common
use for XSL FO already.

Please see above for the encoding considerations. Perhaps you should re-
fer to the application/zip registration here.

Same as above.
