Note: There is a newer version of this specification see VEC 2.0.2
A UsageNode represents a position in an abstract vehicle, but it does not imply a certain location in space. For example, the "Head Light Left". UsageNodes belong to the master data and they are defined on some companywide level. They can be used to enforce consistent naming over different projects and different development streams (e.g. between Geometry and Electrologics).
A UsageNode can be realized by different elements in the VEC (e.g. NetworkNode, OccurrenceOrUsage, TopologyNode, ComponentNode).
