 * defined by a parser. These will be implemented by classes implementing the corresponding
 * immutable interfaces, so we don't have to put setters in the modeling API.
 * 
 * Objects of this kind should be created by the IResolver passed to the parsers, and
 * implementations will know what to do with them to turn them into "active" model
 * objects.
