SYSML2 — Example FrontAxle definition

In A.3 Definitions, in the diagram in Figure 58, the feature FrontAxle::steeringAngle is shown subsetting ISQSpaceTime::angularMeasure. However, in the corresponding textual notation representation, steeringAngle is shown as subsetting ISQ::planeAngle. Now, ISQ::planeAngle is actually an alias for ISQSpaceTime::angularMeasure, so the representations as shown are technically correct. But the difference will be likely be confusing to the reader. Perhaps, at least, the ISQ::planeAngle should be changed to ISQ::angularMeasure in the textual representation.
