<Table ss:ExpandedColumnCount="1" ss:ExpandedRowCount="3"
x:FullColumns="1"
x:FullRows="1">
<Row><Cell><Data ss:Type="Number">2</Data></Cell></Row>
<Row><Cell><Data ss:Type="Number">2</Data></Cell></Row>
<Row><Cell ss:Formula="=SUM(R[-2]C, R[-1]C)"><Data
ss:Type="Number">4</Data></Cell></Row>
</Table>
I wonder how many of the ss:Formula expressions are convertible to XPath
expressions?
The following uses absolute, not relative references, which is wrong:
<Data xforms:calculate="../../../Row[1]/Cell/Data +
../../../Row[2]/Cell/Data "></Cell>
