Yes, the core PIM-SM IPv6 functionality is included in XORP, so if
you are planning to run XORP then you don't need to run pim6sd as
well.

However, to be fair currently XORP doesn't implement MLDv2 (yet) so
if you have IPv6 SSM receivers, you would have to run pim6sd as the
last-hop routers connected to the receivers (the XORP routers should
be fine as intermediate PIM-SSM routers).
