Remarks

DSL model elements support property change events through their custom property descriptors.

These model elements are used, for example, by WPF data binding. However, they are not very convenient for programmatic use. Furthermore, if Visual Studio supports the "traditional" INotifyPropertyChanging or INotifyPropertyChanged interfaces, WPF prefers them over the property descriptor for two-way binding which fail because they do not use implicit transactions. Therefore, Visual Studio DSL model elements implement the traditional events without implementing the interfaces themselves.
