Issue 6367: Combining joined tokens (uml2-superstructure-ftf)
Source: NIST (Dr. Conrad Bock, conrad.bock(at)nist.gov)
Nature: Revision
Severity: Significant
Summary: Join nodes should have an option to combine tokens with identical
values.  For example, when joining flows created by a fork duplicating
tokens.

Resolution: see above
Revised Text: 
Actions taken:
October 20, 2003: received issue
March 8, 2005: closed issue
Discussion: 
In Figure 190, add an attribute to JoinNode:
isCombineDuplicate : Boolean = true.
Updated Figure 190 shown below.
In JoinNode class:
Rename “Attributes” section to “Attributes (CompleteActivities)”
in Attributes (CompleteActivities) section, add this entry:
“isCombineDuplicate : Boolean [1..1] Tells whether tokens
having objects with the same identity are combined into one
by the join. Default value is true.”
in Semantics section, before the last paragraph, in its own paragraph, add:
"If isCombineDuplicate is true, then before object tokens are offered
to the outgoing edge, those containing objects with the same
identity are combined into one token."
