Martin, seems like a plan (heh) we can discuss on today's call at least. 
Hopefully both you and Stephen can make it.

extensions or provider-specific information (such as a parameterised 
plan). Perhaps ..., e.g. #required (i.e. highly desired) and #optional. 

Certainly seems reasonable at first blush that Automation could make that 
predicate's object a resource with it's own properties, and seed it with 
those you propose which I interpret basically as usage hints.  Let the 
"spirited naming discussions" commence [ducks, as he always does for 
those] on the predicate.

extensible to other executable things, like Actions, although that 
wouldn't be interoperable/backwards-compatible. 

To make use of a Plan, you also need a collection capable of fielding 
create requests for that Plan.  So this seems incomplete as written. Using 
the same resource "trick" that I mused about on Plan would allow that, 
even if the "shape" in this context is different.  That's allowed.

One way to solve the compatibility issue (which, to be precise, is an 
*implementation* issue not a spec issue, if the spec's Range is Any per 
Core's guidance) would be to make it multi-valued, and make the semantic 
that each of the possibly multiple values is functionally equivalent; a 
client should choose at most one, presumably the one that it understands 
best, if >1 are offered.  If Automation provides one way to use that as a 
current basis for wide interop *and* allows others for future extension, 
implementation-specific extension, and/or implementation compatibility, 
that seems like a pretty good situation.



Best Regards, John
