SYSML17 — 7_cannot_redefine_boundreference is too constrained

Standard says.... "BoundReferences shall not be applied to properties that are related by redefinition to other properties with BoundReference applied"

This constraint seems very arbitrary... BoundReference could be used akin to an alias... which allows one to use it as another layer of indirection... BoundReferences should be allowed to refer to other BoundReferences so if the "other BoundReference" changes one does not have to change the first one which refers to it
