Create a DSML interface for Set references
Current Situation.
The ModelElementPropertyLiteral references the set to which it refers. In the MOEA plugin, a similar DSML extension is used that must have the same field.
Proposed Improvement.
Define an interface the specifies the set reference (such as a IBoundExpression) to avoid code duplication and potentially broken APIs.
