XMLFoundation provides a foundation for XML support in an application. However, it is more than just another XML parser. It applies a unique approach to handling XML that allows your application code to focus on the application rather than traversing DOM or subscribing to SAX events. The most unique feature of the XMLFoundation is the object oriented encapsulation that provides XML support in the application layer. XMLFoundation allows you to easily integrate XML with your GUI or with your server objects, and it natively supports COM, DCOM, and CORBA objects.
