Detailed Description

XPConnect has magic to transparently convert between nsIVariant and JS types.

We mark the interface [scriptable] so that JS can use methods that refer to this interface. But we mark all the methods and attributes [noscript] since any nsIVariant object will be automatically converted to a JS type anyway.
