Yes, this is true. However, as seen in my example I posted, TAL has a
concept of local and global variables set within one interpretation
session. So occasionally you will see something like <p
tal:content="someVariableSetPreviously"></p>.
As a matter of fact, I had originally written a WebKitEngine for
processing TAL that placed all of the page's member variables and
functions into TAL's local namespace. So instead of saying <p
tal:content="python:page.myFunction(5)"></p> you could say <p
tal:content="myFunction(5)"></p>. However, this involved crawling the
page's inheritance hierarchy looking for variables and functions to
insert into the namespace, and I decided it was more important to stick
to the TAL syntax than it was to save typing python:page.
I really encourage people to download TAL and try out my implementation
of TALPage. It's surprisingly easy to use and very powerful.
