OCL25 — Complete OCL document must be a Package

In order for a UML model to import some Complete OCL for use in the model's constraints, a Complete OCL document must be a (derived) Package. Any tool can therefore import Complete OCL using its conventional metamodel import syntax; just needs per-tool support.

Complete OCL documents must not conflict. For instance if MM imports COD1 for its own purposes and then your usage imports MM (and COD1) and also COD2, the declarations in COD2 may not introduce anything that requires re-analysis of the OCL expressions in MM or COD1; the only change to MM+COD1 execution may arise through additional derived virtual functions.

Avoiding conflicts requires some strong WFRs.

Once conflicts are avoided, Complete OCL documents can be pre-compiled and loaded in compiled form.
