The annotation isn't inside the arg tag. It's inside the method, signal or 
property tag. And it takes an identifier (In0, Out1, etc.) because the 
annotation is not allowed inside the arg tag.

The spec is clear: "Method, interface, property, and signal elements may 
have "annotations", which are generic key/value pairs of metadata."
