Yes, you're right.
as of 12.0(26)S/12.3/12.2(18)S this command has been extended:
domain-id [[<ip-address>] | [Null] | [type <type-value> value <hex>]]
Null - no domain-id is associated with the process
type - one of the values 0005, 0105, 0205, 8005
value - 6 bytes hexadecimal value
secondary - secondary domain-id
by default domain-id is equal to the process id associated with the OSPF
vrf instance. 0005 is used as a domain-id type.
Domain-id is an 8 byte identifier that idetifies OSPF domain of the
prefix. When OSPF route is
redistributed to BGP VPNv4 route in the MPLS VPN context, Domain-id
extended community is attached to the BGP update. Domain-id is used on
the egress PE, when BGP VPNv4 route is redistributed to OSPF to decide
what type of LSA to generate as a result of the redistribution of the
BGP VPNv4 route.
