A UsageNode represents a position in an abstract vehicle. 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 Electrologic).
A UsageNode can be realized by different elements in the VEC (e.g. NetworkNode, OccurrenceOrUsage, TopologyNode, ComponentNode).
