I disagree here. In general there is no need to know
about the XML structure since the XML serialization 
is meant for exchanging RDF models (at least that is
my point of view ;-).  If you look at the examples of 
M&S you won't find an RDF graph containing a reification
or bagification unless bagID or propertyID are explicitly
given. In my opinion a parser SHOULD provide a configuration
setting that enforces a bagification for every rdf:Description
element (if someone really is interested in the XML structure
of the serialization...)      

All the best,
