[1] The query isDistinguishableFrom() determines whether two BehavioralFeatures may coexist in the same Namespace. It specifies
that they have to have different signatures.

The list of owned parameters describes the order, type, and direction of arguments that can be given when the BehavioralFeature
is invoked or which are returned when the BehavioralFeature terminates.
The owned parameters with direction in or inout define the type, and number, of arguments that must be provided when invoking
the BehavioralFeature. An owned parameter with direction out, inout, or return defines the type of the argument that will
be returned from a successful invocation. A BehavioralFeature may raise an exception during its invocation.
