[Zope] DTML reformulated as XML (was RE: [Zope] <% ... %> ?)

(First let me appologize for the junk I spewed to the list a couple days
ago... it was late and I must've hit send when I meant to save as
draft.)

That's a very good point.

I've written most of a proposal for a XDTML syntax, and I should be
posting it tonight... this is the exact suggestion I made.  Actually,
split the if into an if and a choose, just as XSLT has it.  The if
doesn't allow for any else or elseif conditions, but the choose does. I
think it's a rather clean solution, and I suspect the authors of the XSL
draft agree with me. :)
