hmm, I could live with this - but where do we find the definition of 
"FO Fragment of RDFS" -- if we can define that clearly things would 
work well -- maybe something like



OWL  Full -----  OWL DL
  |                 |
  |               OWL LITE
  |                 |
RDFS  -------- FO Fragment of RDFS

in fact, if we added the OWL Lite vocabulary in the first column this 
would be what we once called the "two dimensional" view of OWL and 
its restrictions, which Guus had proposed and we thought might be too 
complex to describe.  Maybe adding it back in (i.e. make Lite a 
vocabulary restriction on either Full or DL) would work -- IMHO we 
need to do something to clarify some of this if we're going to make 
it to/through PR
