Not sure how relevant it is to this discussion, but...
have you looked at Nevow?
http://www.divmod.org/Home/Projects/Nevow/
(just the template language, not talking about the other
neat stuff like Stan, Formless, Webform, or LivePage.)

The template language is an attribute language but is
almost featureless compared to TAL/TALES/METAL.
E.g. 
	<span nevow:render="foo" />

...will invoke a method of the class named render_foo(data, context).
The python class declares which template it will use, not the
other way around.

AFAICT there are only 4 attributes:
nevow:render, nevow:data, nevow:pattern, and nevow:slot,
and they only accept string identifiers as values.

I haven't played with it much and don't really grok it yet
but it has a certain minimalistic appeal.
