With the important nuance is that if you don't want to do it (and I understand the reasons you write) we would still need a more general 'assessment' motivation, so we can attach the motivation in the DQV namespace to something in the WA namespace using skos:broader, as it would fit for a good extension of the WA motivations.

I am trying here to have DQV comply with the recommendations on extending motivations:
"The skos:broader relationship SHOULD be asserted between the new Motivation and at least one existing Motivation, if there are any that are broader in scope." [1]

Honestly I'd be a bit reluctant to have WA depend on the content of another voc that's not a Rec.

Actually, I believe we should comment on their spec; I am indeed not sure that the approach they took (subclassing an annotation, instead of 'just' defining a different motivation) is the right approach. I am definitely in favour of a motivation instance, ie, the approach that you guys preferred, and this is what they should do in the DQV document.

But that is only cosmetics. The practical issue, however: that document is "only" a WD. I am not sure when the intend to go for a Rec, ie, whether we can normatively refer to them.
