general: This specification defines the authorizations for Common Cartridges and the roles to be used for selective display of resources to Learner or Instructor. This group is defined exactly as in IMS Content Packaging v 1.2. Any namespaced element from any namespace may be included within an "any" element. The namespace for the imported element must be defined in the instance, and the schema must be imported. The extension has a definition of "strict" i.e. they must have their own namespace.
