Currently, @armCommonDefinition can only be applied to model. This leaves out a number of enum/union types out of $ref to common-types. To achieve full reference-ability, we should enable this capability. It is arguable that most spec would not directly reference these sub-types in the common-type swagger, but in reality there are few specs do today (around ManagedServiceIdenitityType). There could be future cases as well.
