UML14 — UML 1.4: Transition containment problem

According to the UML 1.4 standard, a Transition [UML 1.4, pp. 2-147] is
contained either as an "internalTransition" in a State, as a "transition" in
a StateMachine, or as an "ownedElement" [UML 1.4, pp. 2-13] in a Model,
Package, Artifact, Node or ClassifierRole (other containers excluded because
of restrictions they make on the "ownedElement" containment in their
wellformedness rules). The latter containment does not seem to make a lot of
sense.

The question is: is the containment of a Transition as an "ownedElement"
intended? If so, please explain the meaning of e.g. a Transition contained
directly in an otherwise empty Package.

If not, it should be stated unambiguously so in the wellformedness rules for
Transition, e.g.:

self.namespace = null
