Marc,

One of the reason for changing RDF Schema on this issue is that using
the conjunction view can lead to inconsistencies when combined with
multiple inheritance. A small document that we wrote about this in
April of this year can be found at:

http://sesame.aidministrator.nl/doc/rdf-interpretation.html

Chapter 4 is about the rdfs:domain and rdfs:range properties.

I hope this will convince you that disjuction is the way to go, even
though it has some drawback from a modelers point-of-view.

Cheers,

Arjohn
