The main advantage is that XQuery can also query anything else represented 
in XML. Since RDF is only part of the web, and XML is another really big 
part of the web, it is useful to be able to do queries against both RDF and 
XML using the same tools, and to be able to correlate information across 
the two. This is especially true since RDF often describes XML sources.

Also note that it is no harder to convert data into triples that do have a 
syntactic representation than it is to convert data into triples that do not.
