Default MDT in Multiprotocol VRF

I'm trying to set up a Multicast VPN and encountered the following problem:

Given a single-protocol IPv4-only VRF I have the possibility to configure this:

     PE1(config)#ip vrf VRF123
     PE1(config-vrf)#mdt default

When I upgrade to a Multiprotocol VRF there is no way of using "ip vrf" command because it says:

     PE2(config)#ip vrf VRF123
     % Use 'vrf definition VRF123' command

That's no big deal but with "vrf definition VRF123" I can not specify any mdt command:

     VPN Routing/Forwarding instance  configuration commands:
       address-family  Enter Address Family  command mode
        default         Set a command to its defaults
        description     VRF specific description
        exit            Exit from VRF configuration mode
        no              Negate a command or set its defaults
        rd              Specify Route Distinguisher
        route-target    Specify Target VPN Extended Communities
        vpn             Configure VPN ID as specified in rfc2685

Does anybody know if I can find it somewhere else for a Multiprotocol VRF or if I don't need it any longer (which I doubt) or if there is any workaround?

By the way I'm running this: Cisco IOS Software, c7600rsp72043_rp Software (c7600rsp72043_rp-ADVENTERPRISEK9-M), Version 12.2(33)SRD4, RELEASE SOFTWARE (fc2)

Thank you in advance!

Great! It seems like only posting the question makes the brain free for new investigations. I found the answer... Sorry for stealing your time

For those who are interested in my blindness:

     PE2(config)#vrf definition VRF123

     PE2(config-vrf)#address-family ipv4

     PE2(config-vrf-af)#mdt default

All the best!
