You mentioned that you'll submit these specs as internet drafts once
you've got ELEMENT and ATTLIST declarations figured out. I'm willing
to help. But...
>EMBED can take arbitrary attributes.
I believe this is not expressible in SGML. To write the DTD, we have
to know the list of possible attribute names. This issue came up
in discussion of the APP element as well. (Dan surfs the archive...)
Ah! Terry Allen crossposted something from the Java List:

OK... so now we've got:
<!ATTLIST EMBED
SRC CDATA #REQUIRED
HEIGHT NUMBER #IMPLIED
WIDTH NUMBER #IMPLIED
>

I gather this is a description of the content model of the NOEMBED
element. It's not quite enough detail for me to write an ELEMENT
declaration: could you sketch the content of EMBED and NOEMBED in some
notation that you're familiar with, like yacc or BNF?

p.s. Mark Gaither: you wanna start hacking up a DTD to describe these
extensions and stick it on the validation service so everybody can try
them out? I know you're busy... if you're too busy, is there anybody
else who runs a clone of the validation service who wants to try
it out?
Maybe I'll get a clone running on www.w3.org. I need to do that
for the conformance testing anyway.
