Yes, that's what I mean. Clearsilver is a good example. There are
- the data structures are platform-independent (they can be encoded in
JSON, C, python), and they can be easily converted from one language to
another, even to and from XML, this simplifies the transport too (e.g.
in Ajax, webservices)
- the template does less, it does not need to know anything about zope,
it works faster, the data access from inside the template is not an
access to the ZODB ...
- it is possible to create a simple schema definition from the data
structure itself (this is what I've done in the Ajax toolkit I'm writing)
- the template itself is truly platform-independent

The StringTemplate guy has an interesting take on
templating and model/view separation:
Particularly the stuff about the five rules implied by
strict model-view separation.
conceptually the idea is:
write your template once and deploy it on your server, on your client,
in your UNIX scripts, etc.. (that's basically the idea with XSLT, except
that not many feel that XSL is easy to write).
I think that the principles stated in that article, of clean separation
between model and view (called "encapsulation") are more important than
the template's actual syntax. But the syntax is important too since
it's humans who write templates ..
