Ok, I see what you're saying.

Still, you cannot define a networking type for a pseudo wire until
mpls encapsulation is enabled.

I just tested what you suggested and the output for `show mpls
l2transport vc 821 detail' is the same whether I use a pseudo wire
class like you suggested, or I simply define encapsulation mpls on the
interface level.

pseudowire-class vltun-ethtun
 encapsulation mpls
 interworking ethernet

interface GigabitEthernet2/20
 mtu 9216
 no ip address
 speed nonegotiate
 xconnect <remote IP> 821 pw-class vltun-ethtun
end

show mpls l2transport vc 821 detail
