Before people get a heart attack about more action types, I am not 
completely wedded to the concepts Capability Action and Message 
Action. However, what I am trying to do is complete the connection 
between a participant's actions in sending and receiving messages, and 
the actions that are viewed as being service actions.

In particular, Capability Action is supposed to refer to the actual 
invocation/activation of the capability behind a service.

The association class "participates" is not spectacularly named; but 
it is intended to refer to the qualified aggregation relationship 
between a joint action and the individual participants' roles in it.

This diagram does not define "counts as"; but uses it. If we really 
need to model it then I will have a go at doing that.

Note that one of the key merits of this model is that it allows us to 
talk separately about what is happening at the service level and at 
the communication level; and yet at the same time establish the 
connection. This is key because the natural conversations about 
messages etc. (e.g., MEP, end points, etc. etc. ) is disconnected from 
the natural conversation about services (policies, RWE, action 
sequences etc. etc.).
