Before hacking away on the Z2 page template implementation, you
should have a look at the Z3 page template implementation -- the
stuff in zope/pagetemplate might already meet your goals since the
Z3 appserver specific stuff is all supposed to live in
zope/app/pagetemplate (and the docs and test suites appear to agree).
It is also an easier place to fix problems you discover, since you
don't have to worry about backwards compatibility so much.

The Z3 page template implemetation just depends on
zope.tal, zope.tales and zope.interface - it should be a nicely
packaged/packagable implementation that works for Z3 and outside
of Zope. I don't know if it is worth backporting this to Z2.
