Note: There is a newer version of this specification see VEC 2.1.0

Specification for the description of a part structure. This specification defines what PartOccurrences are actually in the bill of material of the described PartOrUsage. This is necessary, because it is possible, that for a definite description a Part more PartOccurrences are needed than the ones that are in the bill of material (see CompositionSpecification).
