  "Description": "Supports the definition of sets of properties on objects.\nObservers can listen to changes on individual properties or the\nset as a whole. The properties are meant to be fully\nself-describing. In support of this, there is a framework for\ndefining enumerated types, as well as other bounded types, as\nS4 classes.",
