OK, then 'format' is a script that takes the output of 'keys', 
passes it to 'sort', and returns the result? If it's ubiquitous, 
fine .. otherwise, I like the 'dummy' route sans helper scripts 
more.

Is '<li tal:content="licenses/key" />' a feature deriving from 
the proposed changes? As is, it raises a KeyError on 'key'. So 
one has to '<li tal:content="python:licenses[key]" />'. Hmm, I
think we're stuck with the "python:" there ..
