@keys in

<topicsetref> points to a <topicset> element in a DITA Map.
As per my understanding, a key identifies/points to a Map/Topic.
So, if a key is defined on <topicsetref> (using @keys) what shall it refer to?

  I think, @keys does not make sense on <topicsetref>, as it points to an element inside a Map (and not to the Map itself).
Hence, @keys shall be dropped from <topicsetref>.
