Sorry, you can't just invent a MIME media type. There are a few RFCs for
MIME media types which specify how your media type has to be named and
how to apply for an IANA registration. More info can be found at
http://www.iana.org/assignments/media-types/ . There also is a
specification how unofficial MIME media types have to look like in case
you don't want to register them.
