ORA-21700 error using sys.xmlType in Oracle 9.2

Question

I'm working on an application which uses the XMLType column in some of its database tables. When we started, we were using Oracle 9.0.1, and this test code works (which emulates how we have to, in some occasions, populate the XMLType column).
However, we installed Oracle 9.2.0.3 on the same machine and created database instances using this version of Oracle. We didn't upgrade the original 9.0.1 installation (which still exists side-by-side). When we run this code, we get the following exception...
java.sql.SQLException: ORA-21700: object does not exist or is marked for delete
ORA-06512: at "SYS.XMLTYPE", line 0
ORA-06512: at line 1

This exception occurs after we've written the data to a Clob and are attempting to call createXML to update the column.
Is there anything additional I need to do to get this working in Oracle 9.2 again? Thanks.

I've found this....
http://download-west.oracle.com/docs/cd/B10501_01/appdev.920/a96620/xdb05obj.htm#1032058
Does this mean that, for a table to use an XMLType column, it has to have a single schema definition for every row in the table?
This won't fit for what we're doing.... that is, our table stores XML data for each row, but they are all different types of XML... they don't have the same structure,they don't use the same schema.
Please let me know if I'm missing something
