Hmm...to be precise, current DSCP values populate just 5 bits.

Oh, but I was asking more than that... :-)
In addition to IPP compatibility, there are 802.1p and MPLS EXP that are also 3 bits. In a complex network that CCIE needs to mess around with, these all come to play and need to interact. Having 6 bits in one place and 3 bits elsewhere is a challenge that needs creativity to overcome -- at least awareness :-). This is what I was aiming for with my question.
I never said that there WAS an incompatibility, take a careful look at how I worded the question. Sometimes question can ask you about something that is wrong and expects you to recognize that... ;-)
I would really like to be a proctor! :-)
