Working with the XML Scheme for Revision Control

To work with revision control, you must write an .xml file for every class which contains the description of the read/write process of the object data (similar to the dwgIn()/dwgOut() methods). If the class is not described, you cannot merge its changes and cannot properly compress subsequent revisions of the object in the database.
