I have a couple of comments on draft-ietf-mboned-64-multicast-address-format-06. (1) Sec. 4.3 RFC 3307 requires the low-order 32 bits of a dynamically-allocated multicast address to lie in the range 0x80000000 to 0xFFFFFFFF. That means the high-order bit of any embedded IPv4 address may have to be flipped. You may potentially need a new flag to indicate this, which means another iteration through 6man. (2) Sec. 3.5 should refer to RFC 5952.
