UMLR — Section: 16.3.1

Delete sub-sections Attributes and Rationale as there are none. I question, in light of Constraint [1] and the second paragraph in sub-section Semantics, that there are no associations for an actor. Both constraint [1] and Semantics clearly indicate that there are associations and the Semantics paragraph even indicates multiplicity possibilities greater than one. Figure 401 shows no navigability and association between UseCase and Actor although both Constraint [1] and Semantics indicate that there should be some. Typo - There are eleven "(" but only ten ")" in constraint [1]. Personal preference - Restate Changes from previous UML to "The additon of the constraint that requires that all actors must have names has been added."
