Silverlight Controls - The path to reusable XAML - Justin myJustin = new Justin( Expriences.Current );

Looks like Justin may have found what I have been looking for - reusable, data bound (sort of) Silverlight controls.

What I don't get is - why XAML?  Why can't we use something other than a string blob to represent a control?

How about embedding data-bound Jelly graphs in PowerPoint or maybe Excel?
