SYSTEM AND METHOD FOR ISSUING A MESSAGE TO A PROGRAM

Described is a mechanism for issuing a.n event notification message, from a first program to a second program, to indicate that an action occurred within the first program, where the event notification message includes a parameter that indicates that the action is one of a group of possible actions. More specifically, in an application configured to edit documents created with the eXtensible Markup Language XML, the occurrence of an XML-related action causes the event notification message to be issued. The XML-related action may be either an XML- related move action, an XML-related insert action, or an XML-related delete action. In this way, a single event notification message can be used to indicate the occurrence of three different types of actions while editing an XML document.
