Ivan, All, Indeed we did not resolve the XMLLiteral issue aka the default data type issue), yet. The rather good news: There is an issue in Tracker, now [1]. The bad one: We still have to decide what we want/need ;) Current status: + We are talking about section '5.1.1.1 XML Literals' in [2] + Mark has put together a comprehensive list of options we have [3] Regarding this issue I have made the following observation that I'd like to discuss with you: Referring to [4], the XML Content within an RDF Graph is quite unambiguously defined. The definition says: 'RDF provides for XML content as a possible literal value. This typically originates from the use of rdf:parseType="Literal" in the RDF/XML Syntax. Such content is indicated in an RDF graph using a typed literal whose data type is a special built-in data type rdf:XMLLiteral, defined as follows ...' amongst other things, the definition contains 'a lexical space that is the set of all strings which are well-balanced, self-contained XML content [5]' Taking the following fragment as an example input <div about=""> <h1 property="dc:title"> E = mc<sup>2</sup>: The Most Urgent Problem of Our Time </h1> </div> I would assert that this does not conform to the definition of a well-balanced, self-contained XML content as of [5] due to the fact that the content of the <div> does not start with an element. Any thoughts?
