Hi Tom,
this exacly was a problem for my design here to:
ZPT dont implement real inheritance :((
I had success with the following workaround:
1) Master Template - this holds the global layout and things
which are common to all pages. Its broken up in small macros
for every constant part.
2) several Temlates for bigger parts of the site, e.g. standard table,
standard question-box etc. Each in a separate template as it seems
convenient, die rest is filled in from master template so it looks
like a complete page - this is just for quick overview
3) Function centric templates - these are for a small group of pages
or even a single page, like a "type of page". They form a big macro,
which covers the whole HTML (actually I use <metal:block> tag around
<html> and strip this in edit-view/ftp/webdav so co-worker cannot
circumvent the macro)
Every constant part is assembled there from macros of the master
template (1) (for example navigation) and macros of the desired
standard element template(s) (2).
Every piece of text which should be localized is surrounded by
define-slots. All other parts remain constant (this also saves
the app-logic from beeing accidently overwritten)
4) The pages which use their function specific template (3) and only
allow the slots to be filled, which are mostly text. Usually there
is one for any language version (I use language negotiation to provide
the relevant content-language to a user, app-functions get their language
selection from surrounded page)
>From what I can tell this works pretty well and avoids to repeat things
too often. (Only the global table structure is repeated because of the
unability to do inheritance)

PS: this thread should be moved to ZPT list I think. (Sorry for the
cross posting)
