[oslc-core] OSLC Compact representation, titles with markup

[Arthur Ryman]

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.

RDF/XML
