Hi David, 

I want to congratulate you for this ellegant solution.

Just a minor remark: in case there are many different values for the
"type" attribute, it would be necessary to split the xsl:sort
instruction into two, each specifying data-type="number".

This is necessary, because when sorted as text "10" comes before "2".

Actually, the buggy processor is MSXML4, MSXML3 produces the correct
result.
