An IFC file header has provision for storing the hash of its contents. However, a reference to an IFC (as in Module Reference) does not make provision for storing the hash of the IFC referenced when the referencing IFC was built. This can lead to mismatched or skewed situations that are not readily detected.
Suggestion: Augment the structure for Module References to optionally store the hash of the IFC that was referenced when the referencing IFC was built.
