Formatting XML Doc for Excel 2000

I have an open question on Microsoft’s developer site but have gotten no response so we’ll have a go on this list but I think they haven’t a clue.

What I need to learn is how do I format an XML document to have multiple worksheets in Excel?

Note that I have been through everything I could find on this topic from Microsofts website and so far, the xml code does not work for me.

Thanks in advance!
