6307 Cannot reimplement a subschema final method in a subschema
Cause
This error occurs if you attempt to reimplement a method that has the subschemaFinal option specified in a superschema. This is not permitted, because the subschemaFinal method option specifies that the method cannot be reimplemented in a subschema.
Action
If you want to reimplement the method, remove the subschemaFinal option from the signature of the super-method.
