Yes, so definitely so far the scope if TOSCA simple profile which aims to
be easily mappable to Heat/HOT. Therefore, close integration makes sense
IMO.

Even if the TOSCA community focuses more on features not covered by Heat
(e.g. the "plans" or workflows which would rather map to Mistral), the
current decision would not preempt such movements. An overall TOSCA
description is basically modular where parts like the declarative topology
could be handed to one layer - this is what we are talking about now - and
other parts (like the flows) could go to a different layer.
So if we get there in the future, this "decomposer functionality" could be
addressed on-top of a layer we are working on today.

Hope this helps and does not add confusion :-)

Thomas
