Did I write anything about 'important'? I'm just reporting the sad
fact -- which you seem to already know -- that JAX-B is not, and does
not try to be, complete. It does not even have an extension mechanism
to allow you to add additional bits that are important to you but
didn't feel important to KK et. al. when he designed it.
