This would be fine with me, *provided* that
draft-wijnands-mpls-in-band-wildcard-encoding will add the encoding
of two new mLDP TLVs: Transit IPv4 Shared Tree TLV, and Transit
IPv6 Shared Tree TLV, as these two TLVs are required by the mechanisms
defined in draft-rekhter-mpls-pim-sm-over-mldp.

Yakov.
