RE: [xsl] a*b, sum(c*d), sorted on <sort>

["Andrew Welch" <awelch@xxxxxxxxxxxxxxx>]

I would use a use a temporay tree containing a sorted list of <item>
with the first part of the calculations complete, so you would have
something like:

<root>
  <item><a*b>20</a*b><sumCD>18</sumCD></item>
  <item><a*b>6</a*b><sumCD>40</sumCD></item>
  ....

Then produce your table by applying-templates to the temporary tree,
using sum() on the <sumCD> element to get the cumulative column.
