No dynamic XAML?
Let's assume for a moment, that XAML is HTML "done right" for rich clients (suspend disbelief if you have to). It apparently has SVG like elements, if nothing else. It doesn't have CSS, but apparently there are other ways of solving similar problems being proposed.
Apparently, one can embed small amounts of code in the markup. Unquestionably controversial, but often handy. This corresponds roughly to the role that JavaScript plays in HTML... or does it?
What about Dynamic HTML? Namely the ability to modify the rendering and content of the document on the fly? Isn't that lost by a compile to bytecode approach?
