Danny,

Been talking with Dave Ellis and here are a few quick thoughts:
- not clear what it means for the listener to be an Actor (capable of  
action) and not a Participant (an actor who is also a Stakeholder)
- Credibility depends on who is assessing it and is not a part of  
actor/participant although (1) the things that you have as part of  
credibility are attributes of the actor/participant but I'm not sure  
if composition is the best relationship, (2) an assertion of someone's  
credibility assessment (e.g. my credit report) may be an attribute
- Authorization is for an Action, not a Joint Action, i.e. I am  
authorized to send a message regardless of whether anyone receives the  
message; however, it would take Joint Action (as I understand it) to  
cause RWE
- Authorization is a piece of evidence in the assessment of trust,  
risk, and eventual willingness.  Authorization may be necessary and  
sufficient or merely necessary.  The result of a willingness  
assessment based on available evidence may be a request for additional  
evidence.  For example, I apply for a mortgage and am approved but I  
must provide additional documentation (evidence) to prove the initial  
evidence for the approval was accurate.
- Authority is not a composite part of actor/participant/stakeholder  
but rather an attribute based on external entities, e.g. the social  
structure.
