I'm not sure I understand what you mean by 'the english specification' 
-- see below for detailed questions.

Attribute uses are components which are always paired with attribute
declarations, and the latter carry the annotation, if any, associated
with an <attribute> element -- where specifically do you see an omission?

Again, in the first two cases I think you're misreading, and the
annotation is captured, but in the final (<element ref=.../>) case I
think you're right, there's a bug.

That is certainly our goal.

Unless I've misunderstood, one bug only.
