["Peter Foley" <peter.foley@xxxxxxxxxx>]

I hope you can help with a tricky problem.

I have a table format e.g.

<Table>
     <Heading>
          <Column>
               Male
          </Column>
          <Column>
               Female
          </Column>
     </Heading>
     <Rows>
          <Row>
               <Cell>
                    Employed
               </Cell>
               <Cell>
                    1-1
               </Cell>
               <Cell>
                    1-2
               </Cell>
          </Row>
          <Row>
               <Cell>
                    Not Employed
               </Cell>
               <Cell>
                    2-1
               </Cell>
               <Cell>
                    2-2
               </Cell>
          </Row>
     </Rows>
     <Cells>
          <Data id="1-1">
               10
          </Data>
          <Data id="1-2">
               20
          </Data>
          <Data id="2-1">
               30
          </Data>
          <Data id="2-2">
               40
          </Data>
     </Cells>
</Table>

As you can see the id of the Data tag identifies the cell the data is put in. I
key the data tags on @id so that when I process the Row/Cell I can retrieve the
cell value. This works great BUT now the user wants to aggregate 2 or more
tables. This means that there are now 2 or more Data tags with the same id.

What does this do to Key? Can I say sum (Key("data", value))?
