Hi Mary,

I would not go that far with my notes. I agree in general with  Robert's two
layers and even with one language for both layers. My notes were more about
constraints architecture/model. I just tried to clarify some issues with
template layer and investigate differences between template and expression
layers. I am ready to "merge" constraint templates with class templates. I
prefer to keep my notes in "discussion" area.  Do we have a topic map for
TMCL issues/discussions?

I can see some of my notes as "wish list" or requirements for template
layer. I will try to make them more suitable for requirements document.

Thank you,

Dmitry
