Currently the following error is given out -
"WARNING: TrackedResourceValidation - Tracked Resource failing validation is: Application. Validation Failed: 2. 
Tracked Resource must have:
   1. A Get Operation
   2. A ListByResourceGroup operation with x-ms-pageable extension and
   3. A ListBySubscriptionId operation with x-ms-pageable extension.
   4. Type, Location, Tags should not be used in the properties."

IMO, there are already rules for each individual items listed above. So the violation message should be given separately for each of the above.
