Re: extensions of text/enriched

I think Luc's analysis is quite trenchant, and I'm inclined to go along
with his suggested changes.  

As for the continued utility of comments, I can still see a limited
utility, e.g.:

<comment>This is enriched text, composed with FOOBAR version 1.2.  If
you'd like to see MIME messages as you've never seen them before, send
your credit card number to..... </comment>

I have a mild preference for keeping the comments mechanism, but only a
mild one.  -- Nathaniel
