Can one rename a tablespace?

From Oracle 10g Release 1, users can rename tablespaces.
Example:
ALTER TABLESPACE ts1 RENAME TO ts2;
However, you must adhere to the following restrictions:

• COMPATIBILITY must be set to at least 10.0.1
• Cannot rename SYSTEM or SYSAUX
• Cannot rename an offline tablespace
• Cannot rename a tablespace that contains offline datafiles

For older releases, use the following workaround:

• Export all of the objects from the tablespace
• Drop the tablespace including contents
• Recreate the tablespace
• Import the objects
