This seems to work for IPv4 address as I tried the above.  I added the
address and then deleted it.  However, when I attempt to delete the IPv6
address I've given to the interface, I continually get "bad value."  For
example,

ifconfig sis0 inet6 fec0:1:1:1::2/64

ifconfig sis0 delete fec0:1:1:1::2

Which returns:

ifconfig: fec0:1:1:1::2: Bad value

I've even tried expressing all 8 "blocks" of the IPv6 address.  Could this
be a defect in how ifconfig handles IPv6 addresses?  If so, whom do I
contact to look into it?
