I 
have, for engineering values where the convention is that 4.0m and 4.00m 
represent different concepts (packing value, tolerance and units into the same 
string), used single attributes specifically to prevent people processing them 
using the standard decimal->floating point implementations in XML mapping 
tools. W3C Schema validiation in these cases was not important - the model was 
specified using RelaxNG and a implemented custom data types in Java server 
side.

  It's certainly possible to pack the value and the unit of 
  measure into one attribute and many XML vocabularies do this. However, it 
  makes life a bit more difficult for anyone processing the XML, so two 
  attributes might be better.

    Hi 
    All,<o:p></o:p>
    <o:p> </o:p>
    I am creating a xml schema where 
    I have to making a 'attribute' but can a attribute hold a value and 
    unit.<o:p></o:p>
    My example is FlowRate, let's 
    the value and unit could be 100 GPM.<o:p></o:p>
    Can I have just one attribute 
    for 100 and GPM both. Some times it might be 80 
    cFPS.<o:p></o:p>
    <o:p> </o:p>
    So can a attribute hold both or 
    do I need element here.<o:p></o:p>
    <o:p> </o:p>
    Thanks,<o:p></o:p>
