    The W3C XML Linking Working Group has pushed the 
    <link xlink:href="http://www.w3.org/TR/2001/WD-xptr-20010108">
      XPointer specification
    </link> 
    back to working draft status. The specific issue that was 
    uncovered during Candidate Recommendation was some 
    <link xlink:type="simple"
      xlink:href="http://www.w3.org/TR/xptr#xpointer(//div[@class='div3'][7])">
      confusion
    </link> 
    over how to integrate XPointers, particularly those in non-XML documents, 
    with namespaces.

     It's also come to light in this draft that Sun has 
     <link xlink:type="simple"

      claimed a patent</link> on some of the technologies needed to 
      implement XPointer. I think this is particularly offensive because Eve 
      L. Maler, a Sun employee, served as co-chair of the XML Linking 
      Working Group and a co-editor of the XPointer specification. As usual 
      Sun wants to use this as a club to lock implementers and users into a 
      licensing agreement that goes beyond what Sun and the W3C could 
      otherwise demand. The specific patent is <cite>United States Patent 
      No. 5,659,729, Method and system for implementing hypertext scroll 
      attributes</cite>, issued to Jakob Nielsen in 1997. The patent was 
      filed on February 1, 1996. It claims:
