// Document Object Model (Core) Level 1 ISL

//

//
// Modifs:
//    replaced interface by raise for exceptions;
//    "interface NotMyChildException {}" => "raises NotMyChildException".
//
//    replaced "wstring" (Unicode) for simple "string".
//
//    replaced "int" by "long".
//
//    Reordered interface list and added forward references.
//
//    Added a definition for NotMyChildException, NoSuchNodeException,
//           NoSuchAttributeException.
//
//    Renamed Node:PI to Node:PIS due to clash with PI interface.
