Installed instance of a system element
A component is a piece of equipment installed in the vehicle. It references an element of the library with <systemElementUID> and takes over its geometry and its mass (vehicleElementBaseType); a component has no mass of its own. The same element can be installed as often as needed, e.g. one pump in several places.
Position
The <transformation> places the element coordinate system in the vehicle: it rotates and then translates the element, without scaling (transformationSE3Type). Without <parentUID>, it refers to the global coordinate system. With <parentUID>, the component is attached to another component, e.g. a fuselage or another system component, and its translation refers to that component as described for transformationType.
Components without position
The <transformation> is optional. A component without it is not positioned: its mass counts for the system, but it is left out of the center of gravity. This allows the equipment of a system and its mass to be listed before the places of installation are known.
Only a missing <transformation> makes a component unpositioned. An empty <transformation> positions it at the origin of its parent or of the global coordinate system and should be avoided: give the translation explicitly, or omit the element while the position is unknown.
A component whose parent is not positioned is not positioned either, whatever its own <transformation>.
