Hi there,

i need to model a data object list that contains data elements. I want to add the cardinality [1..*] as specified in the OMG BPMN 2.0 specs page 17, but i can not find a way to do this.

Is this missing or how can i do it?

Thanks in advance,
Tobias

Page 17 of the spec talks about conventions used in the document. The cardinality operators mentioned there apply to UML diagrams that describe the BPMN2 model, not to the elements of the model itself.

BPMN2 only allows you to specify whether or not a Data Type (a.k.a. "ItemDefinition") is a collection or not. It does not allow you to put constraints on the number of items that collection may (or must) contain.

HTH,
Bob
