The same problem also exists for *portions* of the XML document -- even small portions. The problem applies to *any* portion whose corresponding XPath Node tree could vary depending on the parser. Thus I cannot reliably write correct, unambiguous GRDDL transformations that wish to do coarse-grained transformations of XML to RDF, as described here: http://dbooth.org/2007/rdf-and-soa/rdf-and-soa-paper.htm#granularity That sure seems like a problem to me.
