Clarification on interaction identifying an operation

Currently a RoleType can have multiple Behaviors, which can each define an interface (e.g. WSDL definition).

A RelationshipType identifies two RoleTypes which it represents, including the optional list of behaviors for each role, or if not defined, then all of the behaviors associated with a role type are included in the relationship.

Therefore, if we have an interaction that identifies the relationship it relates to, and the 'from' and 'to' roles, I don't believe we have enough information to unambiguously determine which WSDL interface a specified operation name relates to. This is only a problem if multiple interfaces on the same RoleType have the same operation name, which may be unlikely, but is a possibility.
