It would be useful if section 5.2.3 referenced the AES DUKPT standard
(ASC X9.24 part 3).  It provides a modern and extremely efficient way
of deriving a tree that produces billions of derived keys from a single 
base key.

It's a concrete and established standard, as opposed to the slightly more
hand-wavy examples in the re-keying document and in NIST SP-800-108.
