Both of these definitions imply that the PMK is a truncated version of the 
MSK.   Perhaps we can just point that out, and reference 802.11 and 802.16e. 
  There really is not much need to say anything more than that.

Yes.  The term "AAA-Key" has been the source of much confusion.   It took 
quite a while, but at this point, the term is only used once in the EAP 
Keying Framework (in the terminology seciton).

Right.
