[news.eclipse.tools.uml2] Re: correct mapping of a dynamic simulation mo

["James Bruck" <jbruck@xxxxxxxxxx>]

Just to clarify a bit more...

The pins correspond to parameters of the behavior.  An operation is the
specification of the behavior.

Also, your diagram might look something like the following attachment.
