Synchronization Bars

I would like to bring a suggestion update the current Metamodel
(BCSSchema.doc) to include pseudo-states that correspond to synchronization
bars. I believe that they should be at the same level as the start-state and
terminal-state. I understand that this is part of the activity-graph
Metamodel from which the current profile is based. However, they need to
explicitly appear in the current profile to be able to have the
corresponding elements in the schema.

Best regards,
