No, Plone has nothing to do with TAL (although it uses it too)
But nobody forces you to DTML either. You can use python scripts
and ZPT (TAL) is just easy - much lesser to type.

You should avoid that if possible.

DTML is pure horror in this regard. You see every little object/variable
everywhere. All namespaces are a big pile in DTML. You will have
a hard time finding out if a value comes from REQUEST, REQUEST.form,
Property, Object somewhere down the aquisition path or even local
loop and <dtml-with> namespaces.

*shiver* You need to have a good portion of masochism to work with
that ;) But you can call DTML with DTML too. (<dtml-call, dtml-var,
dtml-whatever - all can call other dtml or python script methods)
dtml-return is able to return abitrary objects too. But as said,
its no fun to code like that. You can even call Python scripts
in DTML (and vice versa) and keep the logic of your application
out of the template. Later you can decide if you want to replace
the DTML templates with ZPT templates.
In short, if you dont do application logic with it, even DTML
is kinda acceptable. (That said: no call, set, etc. in it)
