Let me rephrase then.  There's no need to spell our every single tag that is
in the "permitted" group.  We simply say "here are the tags that you MUST
have, here are the tags that you CANNOT have.  Feel free to use any tags not
listed here however the DTD allows them to be used.  As an additional note,
here are the tags that our search engine is "smart" about.  How's that
sound?

Woo hoo, that's got to be HUGE.  ohmygosh, 65K.  Not that long, I guess,
much shorter than parts of the SHR.  :-)

Unreverted tags?  I'm not familiar with the usage of that word in this
context (or, I just don't get it).

Hmm, two ways to treat this.  The file that you sent me isn't really tags,
it's complete structures.  Are we going to restrict based on structures (a
huge set), or tags (a much smaller set)?

Yeah, need to clarify what we're specifying here.  I'm going to try to
produce a blank template here in a couple of minutes, assuming that I'm
awake enough to do that.

I'm not so concerned about mistakes, but more about completeness, and the
ability to not get stuck with bad design.  We do need to be able to adapt
this to DocBook 4.0 and 5.0, as well as XML at some point.

Sounds cool.  Got any ideas on how to build such a thing?  Maybe somebody
can build a starting list of keywords.  Later,
