you are correct.  We are revising the representation of "higher-order
relations", having decided that the representation in 7.3 is not the
direction we want to go.  This will remove some of the confusion
that resulted in these examples being wrong.

This fragment does not conform to the allowed grammar, since
it mixes propAttr with atomic (string) element content.

This was the intended interpretation, and your form is consistent
with the representation we shows in example 7.3.  We intend to
recommend a different representation for higher arity relations
in the next draft, and the example will be fixed to conform to
the permitted grammar.

Thank you for your comments.
