On closer inspection I am certain that @documents ought to be subject
to parameter replacement.

Per 6.2 (Minimal syntax) abstract patterns are resolved by replacing
parameter references "in all enclosed attributes that contain
queries". The @documents in turn is to be interpreted according to the
same production rule as an assertion test.
