   Well, explanation. <dtml-var "xxx"> mens "evaluate python expression
xxx". And if the expression is just a DTML Document object - you'll get its
source.
   To render a DTML object one must calls it: <dtml-var "xxx()">! In case
of <dtml-var xxx> DTML will automagically calls xxx()! This is called "DTML
Magic". :)
