/**
 *  This class provides a simple means to track ID Ref usage. Since id/idref
 *  semantics are part of XML 1.0, any validator will likely to be able to
 *  track them. Instances of this class represent a reference and two markers,
 *  one for its being declared and another for its being used. When the
 *  document is done, one can look at each instance and, if used but not
 *  declared, its an error.
 *
 *  The getKey() method allows it to support keyed collection semantics. It
 *  returns the referenced name, so these objects will be stored via the hash
 *  of the name. This name will either be a standard QName if namespaces are
 *  not enabled/supported by the validator, or it will be in the form
 *  {url}name if namespace processing is enabled.
