The keyword here is "(ideally)". These _typical_ cases are pretty much
restricted to a helloworld-like examples or to a pure men log file
browser ;). Real application templates quickly became complicated and
require full blown scripting engine. Zope/Plone/Trac templates are
good examples of this.

Take a look at, say, http://trac.edgewall.org/browser/trunk/trac/templates
It is not obvious what relative frequency is higher. For other systems
the
situation is similar I believe.

So there should be something else that justifies this multitude of
template
systems. Unfortunately (for me :-) I couldn't find reasonable enough
explanation for this phenomena, except for the fact that it is a fun
to
write template engines ;). Probably not this time either.
