Ok!

BTW: I just found that a "DisjointClasses" construct is already part of 
the current OWL1.0 abstract syntax, see the table at

   http://www.w3.org/TR/owl-semantics/direct.html#3.3

So it seems to me that this problem of a missing RDF mapping for an 
existing DisjointClasses-Feature has always been there in the past.
