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?)
