In MyXaml, for instance, you have to specify the namespace in which the class is found. Adam's approach is to use a factory pattern for each different namespace. For example, a System.Web.UI factory is different from a Systems.Windows.Forms namespace factory. The factory is instantiated via a separate configuration file and an IFormatter interface. Properties are handled similarly. Each factory implements setters and getters for the namespace that it implements. This advantage with this approach is that it allows one to use the same markup to generate a UI on different platforms--client, web, mobile, etc. The disadvantage with this approach is that each target namespace requires implementing a factory and the property getters/setters associated with that UI. With MyXaml, I specifically avoid any knowledge of the namespace and the classes/properties that are implemented in that namespace. Even custom handlers for non-XAML compliant classes and properties are instantiated in such a way that the parser itself is oblivious to the implementation details. As I've mentioned before, the beauty of MyXaml is that it can instantiate any well-formed XAML compliant class. Adam's implementation is rather locked in to UI specific instantiation. Adam's approach is definitely quite interesting. In particular, the ability to alias element tags is very nice. This lets you translate, using a lookup table, Avalon XAML tags, such as Canvas, to .NET classes, such as Panel. It'll be interesting to see where he takes his implementation. I'm curious how support for events, general IList/ICollection management, and data binding will be handled.
