ItemEquivalence
Note: There is a newer version of this specification see VEC 2.1.0
Defines two or more ItemVersions to be equivalent out of the view of a certain company. The ItemEquivalence class will most likely be used by a company to express which PartNumber a certain PartVersion has in the context of other companies (same applies to DocumentVersions). However, for every other company separate ItemEquivalences are needed as the statement of equivalence can be very subjective.
