[c-nsp] ASR903 Service instance MTU

I discovered some difference in configuration towards the ASR1000 
regarding Service instances and BDI's.
I cannot set the mac-address under interface BDI. The ASR1000 does 
support this. Can someone give me some hints how I can set the mac 
adress of the Layer3 frames ?:

interface TenGigabitEthernet0/1/0
  no ip address
  service instance 1802 ethernet
   encapsulation dot1q 1802
   rewrite ingress tag pop 1 symmetric
   bridge-domain 1 split-horizon group 0
  !

interface BDI1
  mac-address 0200.0000.0003 (This doesn't work on the ASR902!, IOS XE 
on ASR1002 does work)
  ip address A.B.C.D 255.255.255.0
!

regards,
Rinse Kloek
