you can, but the concept introduced as of 3.1 (see Ian's
persistent poking at this) is that you would only depend on LSB.
The base pieces (core) remain in because they were documented
in ISO-LSB and it wasn't right to just throw them away, and
they'll probably be reused if we go to a minimal "server profile".
But at the moment apps from 3.1 on are only supposed to need
to depend on "lsb" (of the lowest applicable version).
