I wasn't aware page templates generated any markup on their own.  Yes,
the dtml-tree tag is a mess, thankfully there are viable alternatives.

Maybe valid xhtml and such isn't important to you, but it is to me.

Both the <base> tag, and the Image.tag() method are examples of markup
generated by Zope (which, yes, can be overridden, and that was the
entire jist of my reply).  It may be 99% of people who are accusing
Zope of generating bad markup don't know what they are talking about,
but that doesn't make my examples any less valid.  My understanding of
the markup generation policy is that any and all code which generates
markup of its own should aim for standards compliance, and that which
falls short should be classified as a bug and fixed.  You've pointed
out another piece of the framework which needs help, dtml-tree, but I
don't see any bugs filed against it, perhaps you should do so.
