August 23, 2006: closed issue
Discussion: 
By optional inputs, the filer presumably meant that the lower multiplicity of the input
pins are all zero, perhaps due to being on a CallAction for a behavior or operation with
parameters that all have zero lower multiplicity. The Actions chapter only requires that
values are available on the input pins up to the lower multiplicity, which intentionally
leaves the case of all optional inputs open to the specialized behaviors that use actions
(see InputPin in Actions). If the action is in an activity, the action can be started with a
control flow (see ControlFlow). If it has no incoming control flow, and is not an
exception handler body of action for an ActionPin, the action can start when the
containing activity or structured node does (see InitialNode and StructuredActivityNode).
Disposition: Closed, no change
