This decl represents a user defined constraint.
This is either:
- an imported native constraint
- Similar to an external function declaration. This is a native constraint defined externally, and imported into PDLL via a declaration.
- a native constraint defined in PDLL
- This is a native constraint, i.e. a constraint whose implementation is defined in C++(or potentially some other non-PDLL language). The implementation of this constraint is specified as a string code block in PDLL.
- a PDLL constraint
- This is a constraint which is defined using only PDLL constructs.
