    Description

      The switch to registration of metadata from the global scope to selected scopes is not complete yet, although for all current test cases there are no failures.
      Currently the generated init() method for a factory calls the deprecated SDOUtil.registerStaticTypes for its simple dependencies.
      In the simple case this is just ModelFactory and SDOFactory, but could contain other user generated dependencies if for example
      there were to be an xsd import of another namespace (exposed a gap in our test case set). This would mean that the user generated model dependency
      would also be registered against the global registry.

      It is proposed that all registrations, including the built in models, are made against the helper context provided to the Factory's register method.
      I.e. a state invariant that no models are ever registered against the global registry.

      The pattern of looking up models from within packages is not required, since the code can just refer to each model's singleton INSTANCE (see below for the exception SDOFactoryImpl). Creation of the metadata should be done in the init
      method, and the registration of all metadata (built-in or otherwise) should be done in the register method. It would appear on inspection that no reference to the simple dependencies of a factory need be made in its init method, and simple reference to the dependencies INSTANCE in the register will be enough to ensure that those dependencies are initialised before being registered against the provided scope.

      SDOFactoryImpl does not have an INSTANCE currently. The current proposed solution is to modify SDOFactory to have an INSTANCE, in order that it can behave like an ordinary generated dependency in this new approach.
