   * The parent package is often simply core SBML, identified in libSBML

   * package could conceivably extend another Level&nbsp;3 package and
   * the mechanism supports this.
   *
   * @li The libSBML type code assigned to the object being extended.
   * For example, if an extension of Model is implemented, the relevant
   * type code is SBML_MODEL, found in #SBMLTypeCode_t.
   *
