New Issue: Roles Needed in P-Mode

While the CPP/A TC was mapping P-Mode parameters to existing or new
CPA values, we found that there is only one Role in D.3.3,
PMode[1].BusinessInfo.Role.

Since both parties play a Role, we need to capture them both, perhaps
as PMode.Initiator.Role and PMode.Responder.Role, or else similarly
named parameters under PMode.BusinessInfo.
