      • Action 283 Add an ontology header and a comment to each of the test cases from WebOnt that are prevented from being syntactically OWL 2 DL only be the absence of this header and create content for errata on webont tests / Michael Smith
• Datatypes
  • Draft Proposal: OWL 2 datatypes will have disjointness as in XML Schema (i.e., the datatypes xsd:string, xsd:boolean, owl:real, xsd:float, xsd:double, xsd:dateTimeStamp, xsd:hexBinary, xsd:base64Binary, and xsd:anyURI are pairwise disjoint), as requested in LC Comments 22 and 24.
    • Currently xsd:string, xsd:boolean, owl:real, xsd:dateTimeStamp, xsd:hexBinary, and xsd:anyURI are pairwise disjoint. This separates out xsd:float, xsd:double, and xsd:base64Binary.
  • Draft Proposal: Remove the datatype owl:realPlus from OWL 2, as it was introduced to unify floats, doubles, and other numbers.
  • Proposal: Add named datatypes to OWL 2 - one definition per datatype not in the datatype map, acyclic, as per email from Boris and mentioned in LC Comments 51 and 62.
