Dave/Randy, I was wrong in saying that rdf:parseType="Literal" was required. I verified your statement that rdf:parseType="Literal" is syntactic sugar for a corresponding rdf:datatype attribute by using the jena.rdfcopy utility which converts RDF/XML to N-TRIPLE. The W3C RDF Validation service was erroneously escaping markup on output. The escaping is just an artifact of XML and is not part of the lexical space of RDF literal values. I am including an RDF/XML document and its N-TRIPLE equivalent.
Note that subjects 3 and 4 have identical objects.
