No corrections, I just wanted to add some additional comments 
on the mapref attribute resolution below.

We had consensus that they merge.

Correct.  Michael pointed out that you don't know anything
about the desired semantics of a base specialization, and
it might not be appropriate to cascade (e.g., an id), and
Michael preferred that we err on the side of not cascading
when cascading might have been desired than cascading when
cascading was not desired. 

We figure we'd revisit this in DITA 1.3.
