On IQ2 and IQ2E PIC's, you can remark on ingress with the 
ToS Translation Tables feature.

On the MX running Trio line cards, you can remark on ingress 
with an ingress firewall filter, but sadly, this doesn't 
support EXP or IPv6 DSCP bits.

I like the ToS Translation Tables, but it's limited to 
platforms that run those line cards (which is not to say 
that an IQ2 or IQ2E PIC in an MX-FPC will work - never 
tried).
