Note that DTML support in Z3 is *very* basic, though. There's no 
infrastructure whatsoever for equipping classes with views written in 
DTML. Even if there were, one would lack all the special traversing 
machinery to access view and resource namespaces (e.g. for standard 
template layout). We hope to fix this in X3.1 or so, when we introduce 
DTML2. This will allow scripting for markup-less views, such as CSS, 
JavaScript and the like.

The only DTML we have in Z3 right now is a dull "DTML Page" content 
type, which is roughly equivalent to "DTML Document" in Zope2, and 
SQLScript, another content type which is roughly equivalent to 
SQLMethods in Zope2.

Those are bad examples of content types, really, because they don't 
really store content; they provide executable code. Using them is widely 
discouraged if you want to do any serious development with Zope3. They 
are merely there for people we call "scripters".

Yes, it is in X3 alpha1. Also, we don't use CVS anymore. We use 
subversion now: http://svn.zope.org/
