Vista - WinFS sample: CustomSchema

I have installed winfs beta 1 and I have loaded and built the "CustomSchema"
example. Following the documentation I have also used StoreApi to register
the "Northwind" schema and the handler. The sample works and does what it
should (creates some "order" items in a folder in the DefaultStore)

However....
I was half expecting that the type of the custom items would be "Order" and
not just "Item" when viewed in the explorer. In addition to this StoreSpy
does not seem to be able to view any of the custom properties that are
specified in the schema for the custom "Order" type...
Is this perhaps not the expected behaviour or is it just a limitation of the
beta?

Thanks,
Jarl
