Thanks for the heads-up on this one. I would like to narrow the scope slightly. think the scope of each format should be handled as individual related blueprints. The spirit of mine is to enable the addition of *any* sensible format through a compatibility layer. So I would like to tweak it further to suggest that it should enable implementation of TOSCA, or others. It should be possible to resolve this blueprint with or without the completion of TOSCA support, and the TOSCA specific blueprint cited above can reference the blueprint below as a prerequisite.
I also think we should drop the reference to DSL2 for the time being. If we need to narrow the scope of the proposed spec, we can do that in a single place to simplify matters for those trying to follow where we are headed with this. I am happy to consider all viable approaches, and collaborate to find the one that best suits our collective interests.

Perfect, thanks. If you have no objections to the additional update mentioned above, I will do that today. Otherwise, let's discuss it.
