Indeed, we have much the same problem as HTML had before formalizing the
DTD was pursued, which is "well that's how it looks in (Mosaic|Netscape)".
Simply asking that web browsers "conform" to the HTML 2.0 DTD and HTTP
1.0 spec when it arrives isn't enough since there is more to it than
that. Many people mistakenly think that "you can only inline GIFs and
XBMs in HTML, and NetScape's cool because it lets you do JPG too" - in
fact the HTML DTD makes no such declarations. Emacs-W3 lets you inline
MPEG's after all!
Forms is a tricky area that encompasses HTML, HTTP, and CGI (which also needs
a spec!) and URL's (due to METHOD=GET). Since roughly all the same people
are involved in these areas it hasn't been a problem yet, but as we've seen,
it's not always easy to integrate the MIME-ness of HTTP with the SGML-ness of
HTML with the reserved-character restrictions of URL's with the
strightforwardness of CGI. The way I see it, those four areas could pretty
much develop independently if there was a browser spec that essentially tied
them all together: "the browser will represent form elements like THIS (HTML
issue), encode the results like THIS (CGI and URL issue), and transfer them
to the client like THIS (HTTP issue)". All four elements should be
coordinated to some extent, but what ties them together is the user-agent.

If you're referring to Larry Masinter's spec, the changes required to
HTML were indeed rather minimal, but there were also changes required to
the browser (he submittd diff's for XMosaic) and the server-side
processing (he also submitted a CGI program to parse it).

I'd prefer they not be made optional, just like a MIME mail reader has to
be able to display multipart data separately. It's nontrivial to
implement from scratch, but there are public-code implementations.

I'd be interested in taking this on, sure.
