The comparison is dynamic. The user selects an option, that option is
passed to a formhandler and hence back to the referring method. How
could I not do the comparison in this method? If it could be done in a
python script as you say, why should I inject another layer of
complexity into my application when the one dtml method will do the job?
imho such a problem as selected in selects should have a well documented
solution as many developers will need it and why should each one have to
find the solution for themselves?
I think Zope is the most important technology on the Internet at
present, with the possibility to become really huge, but if every
developer has to search so hard for solutions as I have had to, it will
forever be a niche product.

This code does not work;-). If I always work in the ZMI and do not
collaborate with designers on database web applications where the data
is more important than the presentation, can you give me a good reason
for not using DTML. I find DTML more intuitive than ZPT and once you get
the hang of
the namespace magic thing it is not that bad. The ZPT code above seems
to me more complex and it has defined two new variables, whereas the
DTML only has two variables

And just for comparison, here's the ZPT:
<tal:i repeat="group context/getpastoralgroups"
<option tal:define="thisAbbrev group/thisgroupabbrev"
Stop using DTML ;-)
and a string conversion.
ps. I would use ZPT if I could see a valid reason to do so.
The example above is unfortunatly a bit bad from app design view.
You should either do the comparison in your ZSQL Method
or wrap the call to the ZSQL method in a simple python script.
Then all your ZPT reduces to:
tal:attributes="value group/groupabbrev; selected group/selected"
tal:content="thisgroupabbrev"> Example </option>
Which is imho much better to read then the code above.
All you need to do is to deliver True/False, None/Something
for the "selected" field.
Not doing the comparison in your Template (no matter if DTML
or ZPT) really makes live easier.
You should try to get your Application right independend of
any HTML output. (e.g. you can call the scripts/ZPTs directly
to find out whats going on)
