futureMetadata (Future Metadata)

This element represents future metadata information.

Future data storage areas are xml storage areas that a later version of the spreadsheet application can store data into. So a V2 spreadsheet application may store data for new features that don't exist in the V1 version in a future storage area when saving to a format that the V1 version can open. The V1 version may be able to open the file, but won't necessarily be able to understand data that is stored in a future storage area. So the V1 version may ignore this data, but still round trip it in the file format so that V2 and V1 users can collaborate on the same spreadsheet.
