Allow to explicitly name a schema (originating from a class)

[romalytvynenko]

Having more than one JSON resource with the same name, but with different namespaces, causes "weird" schema names, built using the namespace, to eliminate duplicates.

Is it possible to add an alias or explicitly naming a schema in order to overcome this?

Thanks in advance.
