   The link is simple and strong: what you have in double qoutes is just a
python code! (with some security limitations):
   <dtml-var "here_comes_some_python_call()"> or, for example,
   <dtml-call "REQUEST.set('variableu', another_call())">

   Most of the time they are Zope functions - methods, defined in Zope
classess. They are poorly documente 'cause real Hackers Have No Time to
Document! :)
   Your real source of information is Zope source code. That's another
strong reason to learn Python.
