My understanding is that, yes, it is a complex and expensive way to
implement namespaced XML. The benefit is that there is a common
agreement of the basic structure of the XML data, defined and agreed by
consensus.

The benefit of this is that the XML document should be largely
understandable by all those who can interpret RDF-structured data.

The only grey area is when one starts to encode a new type of data, not
previously covered by another RDF subset.

As has been mentioned elsewhere (some web page I read a week or so ago),
RDF, et al, swell the size of the resultant data object by a significant
amount. The trade-off is between making the XML data-object and the
interoperability (another big word that sounds more important that it
really is :-) of the data
