it depends a lot on the availability of softwares and of standards used 
to create such definitions.

Julien has done some work on using XML schemas in zope3 as you know:

XForms could be a good choice for defining forms too.

I'm using JSON for MVC definitions, because they can be used in 
Javacript without much fuss.
YAML seems to be easy to read  too, etc.
SVG can be investigated too for defining layouts, graphical objects etc.

this is really an area where one should look to see what already exists.

sorry if I'm off-topic.
