Notes and Limitations
The following notes and limitations apply to the Arbortext Editor and the Arbortext Publishing Engine implementations of events:
Be aware that DOM mutation events trigger after the document is loaded and something happens to change the document, not as the document is being read in by Arbortext Editor or the Arbortext Publishing Engine.
HTML-specific features in the W3C DOM Events specification are not implemented.
No mutation events are currently fired for undo or redo operations. Instead the AOMUndo event type is dispatched.
SGML-specific document structures such as ignored marked sections are not supported by the Arbortext Editor and the Arbortext Publishing Engine DOM implementation.
