Hm. As an RDF/XML user, probably yes. As a turtle user, well, it would 
be suboptimal...

Yep.... :-(

Actually, Boris' mail did not refer to rdf:Seq/Bag/Alt and the 
corresponding rdf:_n properties. There might be users out there 
preferring those to Lists, in which case the same issue arises for 
rdf:_n. (But I am not sure at all whether we should are bout those)
