[j-nsp] Ethernet CCC with dot1.q tags

Hi all,
I have an ethernet CCC connection with customer L2 switches on either side
configured. I was doing an unrelated configuration on the switches when I
notice a number of VLANs being carried over the CCC. Since the CE-facing and
the CCC instance are configured with ethernet-ccc encap, as I understand it,
it will not recognize the dot1.q tags and proceed to drop the frames. Is
this an undocumented feature of the CCC whereby a number of VLANs can be
carried across an ethernet CCC provided that the CE-facing interface is
configured with an oversized MTU?
Thank you for your time,
Ihsan Junaidi Ibrahim
