Hm, I don't understand. Wouldn't roundtripping be even more save without
these conditional rules? (Apart from simplifying the RDF mapping.)

Why that? I thought roundtripping is about getting from FS to RDF (abstract
data model, not some specific serialization!) and back again, receiving
(more or less) exactly the original FS-style ontology. But even if
roundtripping goes through RDF/XML, why does it have to be an OWL *1.0*
RDF/XML document?

Personally, I am (and was from the beginning) in favour of the new "typed"
names - with or without punning. :)
