2. Trigger event relationships
   1. Original Text:There is a one-to-many relationship between message types and trigger event codes. The same trigger event code may not be associated with more than one message type; however a message type may be associated with more than one trigger event code.

   3. Suggestion:
      1. Governance #?:The same trigger event code SHALL not be associated with more than one message type; however a message type MAY be associated with more than one trigger event code.
