Adding tests for Typed Data feature.
Adding more tests on typed data feature names (all-optional-features) as well as type hierarchy.
Corrected catalog to make valid against schema.
Adding needed module file.
Allowed an error to be raised if, in the module that produces typed data, schema validation can not be activated.
Also allowed error in a third test.
Some more cleanup.
