Why? Both C# and Java (AFAIR) allow interfaces to extend other interfaces.
Because of the second part of the answer. It is a little bit strange that an interface can extend and implement an interface but a class can only implement interfaces. Also it is a bit weired that i can implement multiple interface but extend only one.
An interface should not implement an interface, only classes should implement interfaces. 'implement' infers that actual executable code is provided that implements an interface. Again, I haven't followed the interface stuff, and sorry for writting without reading the background, but I'm working off the assumption that interfaces are kind of like IDL.
ok: interface extends interface class extends class implements interface
not ok: interfaces implements interface class extends interface
