This association allows all ExtendableElements in the VEC to reference DocumentVersions as "external reference".

This association shall be used for the extension of elements in the VEC with information that cannot be represented in the VEC in an appropriate way but can be expressed in some external format (e.g. a specific symbol for a ComponentNode).

DocumentVersions referenced by this association shall not contain any Specifications.

This association is no replacement for associations with a more precise semantic like the DocumentBasedInstruction or the associations between PartVersion and DocumentVersion.


CustomProperty customProperty 0..* 1 Specifies the CustomProperties of the ExtendableElement.
