Note: There is a newer version of this specification see VEC 2.0.1
A TerminalSpecification can define WireReceptions and TerminalReceptions and on that basis InternalTerminalConnections. A WireReception can reference a WireReceptionSpecification in order to provide technical details about the wires which can be accommodated. A TerminalReception can reference a TerminalReceptionSpecification which provides technical details about compatible cavities and mating-terminals. An InternalTerminalConnection states which WireReceptions and TerminalReceptions are electrically connected. This is especially important in case of a coax terminal.
