Section 6 says:

   (b)  Addresses in which the rightmost 64 bits are assigned the
        highest 128 values (i.e., ffff:ffff:ffff:ff7f to ffff:ffff:ffff:
        ffff) SHOULD NOT be used as unicast addresses, to avoid
        colliding with reserved subnet anycast addresses [RFC2526].

It should say:

   (b)  Addresses in which the rightmost 64 bits are assigned the
        highest 128 values (i.e., ffff:ffff:ffff:ff80 to ffff:ffff:ffff:
        ffff) SHOULD NOT be used as unicast addresses, to avoid
        colliding with reserved subnet anycast addresses [RFC2526].

Notes:

The highest 128 values start at ffff:ffff:ffff:ff80, not ffff:ffff:ffff:ff7f.
