BPMN2 — DataAssociations: How do we support literals?

DataAssociations and Assigments correctly allow mapping between data elements.

Now, there is no way to do a simple mapping of a literal to a data input.

An assignment could be used to solve the problem, but then you are forced to include a dummy sourceRef to fullfil the requirement of at least one source ref.

A simple solution would be to allow 0 zero source refs, and keeping the restriction of the scope of the assignment to the souce refs.

As per 5/4 BPMN team meeting - the issue is valid but to be deferred.

testing comments... sorry

(a) Update the UML metamodel, changing the multiplicity of DataAssociation.sourceRef from 1..* to 0..*
Replace Figure 10.61 (pg 230)
(b) Update Table 10.57 (pg 231)
Change the multiplicity of the sourceRef association to 0..*
(c) Update Tables 10.64, 10.66, 10.71 (schema snippets) to match the updated metamodel
