signal — Documents an internal DAVE-ML signal (value, units, etc.)
This element is used to document the name, ID, value, tolerance, and units of measure for checkcases. When used with checkInputs or checkOutputs, the signalName subelement must be present (since check cases are viewed from "outside" the model); when used in an internalValues element, the signalID subelement should be used to identify the signal by ID (which is the model-unique internal reference for each signal). When used in a checkOutputs vector, the tol element must be present.
