just wondering if DTML is actually a valid form of XML, or a bastardized version of XML created specifically for ZOPE. I've done a little reasearch on XML, and I it seems like DTML tags such as: aren't really valid XML forms. The following would make more sense:

<dtml-var expr="..."/> or <dtml-if expr="...">

This form is also valid. Actually, it makes more sense this way, since items in quotes are python expressions. Zope supports at least 3 different syntaxes that I know about, so it really leaves it up to the developer to support standards like XML if they choose to do so.
