SYSML2_ — ShapeItems have radius feature bound

In the Geometry Domain Library model ShapeItems, in the item definitions CircularDisc, Sphere, CircularCone and CircularCylinder, the radius feature is bound to semiMajorAxis (or semiAxis1 for Sphere). However, because of the constraint featureValueOverriding, this means that the radius features cannot be re-bound to specific values in user-model usages of these definitions, as would be expected. (Note that this can only be seen in the ShapeItems.sysml file, not in the description in the specification document.)
