References the PartRelations that are valid inserts for this ExtensionSlot.

This reference points to PartRelations in order to allow referencing indirectly a PartVersion if the description of individual PartVersions is done with one physical VEC file per PartVersion and to allow the expression of optional inserts, choices etc. However, inserts for an ExtensionSlot are always EEComponents by itself. Therefore, the referenced PartVersion shall have a PrimaryPartType = EEComponent.
