Ensure 'Notational Conventions' text is consistent across all of the ws-ra
specs.

Already highlighted is different wrt Ellipses (but other aspect of this section
should be checked):

An ellipsis (i.e. "�") indicates a point of extensibility that allows other
child or attribute content. Additional children and/or attributes MAY be added
at the indicated extension points but MUST NOT contradict the semantics of the
parent and/or owner, respectively. If a receiver does not recognize an
extension, the receiver SHOULD ignore it.

Ellipses (i.e., "...") indicate points of extensibility. Additional children
and/or attributes MAY be added at the indicated extension points but MUST NOT
contradict the semantics of the parent and/or owner, respectively. By default,
if a receiver does not recognize an extension, the receiver SHOULD ignore the
extension; exceptions to this processing rule, if any, are clearly indicated
below.
