QoS in MPLS using the EXP

Good,

I have searched for information about applying QoS in MPLS using the EXP bit, but in the entries:

http://forum.mikrotik.com/t/mpls-vpls-qos/33458/1
http://forum.mikrotik.com/t/mpls-enabled-router-simple-queues-not-working/57506/1

It seems that it is not implemented yet.

Is this the case, is there no way to use EXP for QoS in MPLS?

Thank you

There have been a few attempts to work around this before. Here is one of them:
