If a removed attribute is known to have a default value, an attribute immediately appears containing the default value and, if applicable, the corresponding namespace URI, local name, and prefix.
This method is a Microsoft extension to the Document Object Model (DOM).
When overriding RemoveAll in a derived class, in order for events to be raised correctly, you must call the RemoveAll method of the base class.
