This is interesting feedback.  I understand exactly the relationship you
describe and I think it makes sense for it to be in scope of the T&P
top-level Project.  My initial thoughts are that it would be an additional
project, although the models themeselves would be managed in the Hyades
Platform Project so that the necessary cross-model and cross-tool linkages
could be inserted.  That said, it would require someone to commit
resources to the additional project and I think we should wait until the
dust settles on the top-level project creation before we go there.
