Hi all,

I'm writing a VBA app to collect data from Excel workbooks and sheets and make a report, also in Excel format. Along with the report, I also need to store metadata on how the report was generated (what data was picked and from where).

If possible, I'd like to store the metadata in XML. So I wonder if it's possible to store XML data somewhere *inside* a workbook, preferably hidden from casual end users. If not, I imagine I could save it in rows and columns on a hidden sheet. But the question is: can I keep XML data inside a workbook? I'm using Excel 2003 and 2007.
