Yep, that is correct. It also doesn't work, because no program should
ever be distributed which uses "experimental" types. The whole x- fetish
is a failed mechanism for avoiding name collision in mail headers --
it never worked in RFC 822 and I haven't the faintest notion why they
were silly enough to repeat the same mistake for MIME content types.

Yes, but it should have been the latter (or, better yet, server/parsed-html).
As far as I'm concerned, there is no value in using the "x-" prefix for
anything.

For the record, I was just describing why things are the way they are, not
advocating the use of the "x-" prefix anywhere. It does seem silly to
end up with "experimental" content types in widespread use.
