Hello Andreas,

          

          

          
allow me to rephrase your answer before I ask questions
            to make sure I understand:

          

            
              
You say theÂuser semantic
                perspective an "empty cell" should be equal to the
                function ISBLANK on the cell is returning TRUE. 

              

            
          

        

      

    
    yes

    
      

        

          

            
              
You say in case of theÂcell
                state being an empty cell (ISBLANK=True), the ODF XML
                element of a table should have no child element
                descendants 

            
          

        

      

    
    No, I am not saying that. The XML has to be able to uniquely reflect
    the fact that the cell is empty, but it does not matter whether the
    table:table-cell element is empty or not. 

    
      

        

          
If this is the case:

          

            
              
Do you desire to 'move' shapes and annotations out of
                the table cell, or shall for cells with shapes or
                annotation the type 'void' be used?ÂÂ

              

                
If the cell is empty (ISBLANK=True) should the XML
                  be an empty XML element <table:table-cell/>?
                  

                  DoesÂit allowÂXML attributes, such as styles (e.g.
                  background colour)?Â

              

            
          

          

          

          
During one of our last TC calls, you mentioned
            "multi-pass" of Gnumeric when loading ODS.
            

            As far I understood, you desired images & annotations to
            be moved outside the XML of a cell.

          

          
Could you explain thisÂto me inÂmoreÂdetail?

        

      

    
    
I do not suggest to move images & annotations outside the XML
      of a cell. It seems that you and other members of the TC are
      thinking of the xml stream as the document. I consider the
      document and the xml stream to be distinct (but of course related)
      objects. The xml stream describes the object. When we read the xml
      stream, we create a document (which once it is created is
      independent from teh XML). When we write the document we create a
      new xml stream.
