Having used XAML recently for purposes not even related to WPF, I can definitively see what this might bring.

XAML is at its core a format to describe an object graph declaratively. The objects can be any .NET object.

The current XAML editor already understands a lot about the objects you describe - i.e. it loads the assembly and introspects the types to give you intellisense while editing. The current one is not without its quirks and bugs, however.

I'd be thrilled to have a new, robust editor that intrinsically understands classes, properties, value converters etc to offer more assistance when writing raw XAML.
