Note: There is a newer version of this specification see VEC 2.1.0

A WireElementReference represents the usage of a WireElement in the context of a PartUsage or PartOccurrence. For contacting purposes, a WireElementReference has WireEnds. KBLFRM-384

Name Type Mult. Description Owning Classifier
identification String 0..1

Specifies a unique identification of the WireElementReference. The identification is guaranteed to be unique within the WireRole.

unconnected Boolean 0..1

If this attribute is true, the WireElementReference is not connected (unused) on purpose. This can be the case for example if a multi core is used, but not all cores are necessary in a specific situation.

However, for all WireElements defined in the WireSpecification a corresponding WireElementReference shall exist. This attribute can be used to mark these unused cores explicitly.
