Another annotation processing example is:

@RemoteHome
public interface RemoteHome extends EJBHome
{
public RemoteInterface create();
}

The above example defines a EJB2.x Remote interface, even though they're not explicitly marked as such anywhere.

Technically, @Remote is used to denote an EJB3 Remote Business View.

That's EJBTHREE-1127, defined by, "EJB3 Core Specification 3.6.2.1":
The return type of a create method on the remote home interface is the session bean's remote interface.
