From RDF Working Group Wiki
Task Force "RDF-XML"
List of the changes considered for the RDF 1.1 XML Syntax Specification.
Changes include the Errata for RDF Syntax
Change 1: typo "tiple"
Syntax typo “tiple” in 7.2.11 Production nodeElement: "and the following tiple is added to the graph"
Change 2: hard coded reference to XML and Unicode versions
Hard coded reference to XML 1.0 and to Unicode 3.0 are unduly restrictive. Both reference should be exchanged against a normative reference to the generically latest versions of both standards.
