XdbConfig.xml and XDB version 9.2.0.3

Question

Since we've upgraded to 9.2.0.3 W2k, Enterprise Manager Console 9.2.0.1 will no longer update the xdbconfig.xml file. Only blanks show up under the configuration section of EMC. This component is aparently not upgraded in the 9.2.0.3 RDBMS patch, and this is one of the problems we've had with it.
Additionally, we have servers with Multiple databases and only default xdbconfg.xml files. This is BAD, because they want to use the same FTP 2100 and http 8080 ports. It appears that the last database started maintains control over the default ports, and if you shut that database down, one of the other instances will take over the ports.
How do you change the xdbconfig.xml file with out using ECM?
I've tried two methods and both have failed.
First simply using FTP logged in with SYS as sysdba, and copying a modified xdbconfig.xml into the root, and then shutting down the database with a restart. This had no effect to the xdbconfig.xml file.
Second I attempted to use the code blurb on Page A-14 in the XML Database Development Guide - Oralce XML DB Part #A99620-02.
Here is the code:
begin
DBMS_XDB.CFG_UPDATE(UPDATEXML(UPDATEXML
(DBMS_XDB.CFG_GET(),
'/xdbconfig/decendant::ftp-port/text()','2101'),
'/xdbconfig/decendant::http-port/text()',
'8001'));
DBMS_XDB.CFG_REFRESH();
end;
Here is the error result:
SQL> @c:\Xdb\changeXdbconfigORG.sql
DBMS_XDB.CFG_UPDATE(UPDATEXML(UPDATEXML
ERROR at line 2:
ORA-06550: line 2, column 22:
PLS-00201: identifier 'UPDATEXML' must be declared
ORA-06550: line 2, column 2:
PL/SQL: Statement ignored
I spent some time tooling around the forums, and I've seen reference to a permissions violation on updateXML, and I've also seen reference that the UpdateXML has to be out side the Begin Block. I've not been able to take advantage of either of references, and make it work. Can someone help me out with this?

Have a look at the xdbConfig.sql file in the zip file attached to the following post...
