Uhm - I can't see these usages... something seems to be off with my IDE
configuration. I did a grep and I now saw the uses. That said, having the
Kind/Location inside AttributedElement still looks weird to me. The "places
where an attribute can appear" is a property of an `Attribute`, not of an
attributed element (which is used to model elements which can have attributes).
