DAML Notations

(... speaking of alternatives to the RDF/XML syntax ...)

Has anyone done work on making a more pleasant ontology syntax for
DAML+OIL [1] ?   

Obviously there are lots of personal preferences.  I'm imagining
something vaguely Java-like:

   Class Animal extends LivingThing, has {
      Animal mother;
      Animal father;
   }

with some clever syntax for cardinality and most of the extra
expressiveness of DAML+OIL in some boolean expression constraint
syntax.
