The author agreed that he will make the change - since it's an RFC Editor document,
I remove my Discuss before the revision.  (The change is to add material differentiating
DSTE from IP Diffserv:

>> There may be differences between the quality of service expressed and
>> obtained with Diffserv without DS-TE and with DS-TE.
>> Because DS-TE uses Constraint Based Routing, and because
>> of the type of admission control capabilities it adds to Diffserv,
>> DS-TE has capabilities for traffic that Diffserv does not:  Diffserv
>> does not indicate preemption, by intent, whereas DS-TE describes
>> multiple levels of preemption for its Class Types.  Also, Diffserv
>> does not support any means of explicitly controlling overbooking,
>> while DS-TE allows this.  When considering a complete quality of
>> service environment, with Diffserv routers and DS-TE, it
>> is important to consider these differences carefully.

  Reference [1] does not talk about the security ramifications of preemption.
  Therefore a paragraph on this topic ought to be added to section 10.
