Extension applies to the content model as a whole; think of adding a new
sequence around whatever's there, and adding new stuff to the end of
that sequence. So:
(a|b) becomes ((a|b), c, d, e...)
I believe you can restrict choices the same way you restrict everything
else -- by laboriously copying over the content model and taking out
only allowable bits. (Restrictions still seem to be dicey interop-wise.
Is this a problem for UBL?)
