/*
 * A MasterPropertySet implements all of the features of a ChainablePropertySet
 * (it is not inherited from ChainablePropertySet to prevent MasterPropertySets
 * being chained to each other), but also allows properties implemented in
 * other ChainablePropertySets to be included as 'native' properties in a
 * given MasterPropertySet implementation. These are registered using the
 * 'registerSlave' method, and require that the implementation of the
 * ChainablePropertySet and the implementation of the ChainablePropertySetInfo
 * both declare the implementation of the MasterPropertySet as a friend.
