Excerpts from ext.ietf-822: 27-Aug-91 Re: Content Types Vincent
Content-Type: INTERLEAF / BINARY (an Interleaf document in binary format)
Again, while I strongly agree with the thrust of Vincent's message
(treat the type and class as independent fields), saying that the class
of INTERLEAF is BINARY is begging the question. What's it an INTERLEAF
(BINARY) version *of*? Here the content-type should be
Content-Type: INTERLEAF-BINARY / TEXT-PLUS (a textual document in
the binary form of Interleaf markup)
Content-Type: INTERLEAF-ASCII / IMAGE (a bitmap in the ASCII form
of Interleaf markup)
Two different formats, two different types. Just saying `INTERLEAF'
doesn't tell you the format type, and just saying `BINARY' doesn't tell
you the document class.
