Personally I hope that they (the WWW community) DO NOT
adopt application/html. HTML is at least eyeballable, unlike RTF,
PostScript, etc. The same can be said of text/enriched.
That was always the way I figured we would distinguish the two cases.
So I think they are both properly named. The benefit of this scheme is
for unrecognized subtypes -- if you see text/foobar, you can show it to
the user with some hope of comprehensibility, while if you see
application/foobar, you probably shouldn't.
