COBCH1604 Cannot inherit from interface '%1$s'

The interface that you are trying to inherit does exist, but there is a problem with its construction.

For example, the following example fails because the interface that is being inherited is empty.

class-id myClass inherits type myInterface.
...
end class.

interface-id myInterface.
end interface.

Add a method or some other valid construction to the interface to fix the error.
