OccurrenceOrUsage
Note: There is a newer version of this specification see VEC 2.1.0
An OccurrenceOrUsage is an abstract appearance of a part in the harness. This can either be a concrete part (with a part number or something similar) or the description (specification / requirements) of a part that should be used at that position. In the first case it would be a PartOccurrence in the second case a PartUsage.

| identification | String | 1 | Specifies a unique identification of the OccurrenceOrUsage. The identification is guaranteed to be unique within the context. For all VEC-documents an OccurrenceOrUsage-instance can be trusted to be the same if the context-instance is the same and the identification of the OccurrenceOrUsage is the same. |
OccurrenceOrUsage |
| aliasId | AliasIdentification | 0..* | Room to specify additional identifiers for the OccurrenceOrUsage. |
OccurrenceOrUsage |
| abbreviation | LocalizedString | 0..* | Specifies an abbreviation of the OccurrenceOrUsage. Normally this a human readable short name. |
OccurrenceOrUsage |
| description | AbstractLocalizedString | 0..* | Specifies additional, human readable information about the OccurrenceOrUsage. |

| referenceElement | OccurrenceOrUsage | 0..* | N | Y | N | 0..* | References the OccurrenceOrUsage for which this OccurrenceOrUsage is an accessory / supplementary component. If an OccurrenceOrUsage defines more than one referenceElement, the semantic is that it is related to the combination all "reference elements" and not to each individually. In other words, in a variable product definition the OccurrenceOrUsage only exists if all referenceElements exist. |

That means, they must have an identical placement, the geometrical models used for each item must be substitutable and the item must be mutually exclusive to each other. |
