That was a bug, see

  http://www.oasis-open.org/committees/relax-ng/errata/spec-errata.html

(which should be linked to from

http://www.oasis-open.org/committees/relax-ng/spec-20011203-errata.html

as referenced from the spec (please fix this, Norm)).

Annotations should be allowed in all elements that don't allow text content.
