Hi Ben,

I am creating XMLSS documents using OWC10, which are supported by Excel2000
and XP, but am wondering if Excel97 can open and interpret the document the
same way that the later versions of Excel can.

If no, can someone give me an example of the error message that the end user
would see?

No - Excel 97 thinks it's just a text file to open, so starts the Text Import
Wizard, which proceeds to show the raw xml in the worksheet.
