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

     It's also come to light in this draft that Sun has

      claimed a patent</em> 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:
