Error deleting registered schema

Question

Hello all,
I have registered a Schema in oracle through PL/SQL with the following script created by Console Management Client:
DECLARE
xclob CLOB;
BEGIN
dbms_lob.createtemporary(xclob, FALSE,dbms_lob.SESSION);
? := xclob;
end;
BEGIN
DBMS_XMLSCHEMA.REGISTERSCHEMA(schemaurl=>'http://www.gimo-armada.es/ICR/ICR.xsd', schemadoc=>:XMLSchemaTextCLobPtr, local=>FALSE, gentypes=>TRUE, genbean=>FALSE, gentables=>TRUE, force=>FALSE, owner=>'DAVID');
DBMS_LOB.FREETEMPORARY(:XMLSchemaTextCLobPtr1);
END;
The schema is registered without problems and the file ICR.xsd can be found in /sys/schemas/PUBLIC/www.gimo-armada.es/ICR
Now, I try to delete this schema with the script:
DECLARE
Res BOOLEAN;
BEGIN
Res := dbms_xmlschema.deleteSchema('http://www.gimo-armada.es/ICR', dbms_xmlschema.DELETE_CASCADE_FORCE);
END;
But the system returns an error:
PLS-00222: no function with name 'string' exists in this scope
I do not understand where is the problem, because the function are in the same package.
The current user has been defined as SYSDBA.
Thanks in advanced,
David.

I think you are still a little confused between namespace and schemaURL or SchemaLocationHint...
<?xml version="1.0" encoding="WINDOWS-1252"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xdb="http://xmlns.oracle.com/xdb"
xmlns:icr="http://www.gimo-armada.es/ORSWE/ICRI"
targetNamespace="http://www.gimo-armada.es/ORSWE/ICRI"
elementFormDefault="qualified" attributeFormDefault="unqualified">So the target Namespace for your XML Schema is 'http://www.gimo-armada.es/ORSWE/ICRI'
I have uploaded the XSD to the folder /ORSWE/Esquemas/ICRI through WebDAV.
I have registered the new XSD with the following script:
begin
dbms_xmlschema.registerSchema(schemaurl=>'http://www.gimo-armada.es/ORSWE/ICRI', schemadoc=>xdburitype('/ORSWE/Esquemas/ICRI/ICR.xsd').getXML(), local=>FALSE, gentypes=>TRUE, genbean=>FALSE, gentables=>TRUE, force=>FALSE, owner=>'DAVID');
end;
/This means that you have also used the value of the namespace as the SchemaLocationHint. This is allowed, but probably not what you intended. Remember to XDB the SchemaLocation hint becomes a key which is can use to look for the XML Schema internally. It is never used as a URL to actally do and look for the schema externally.
I would have exected the schemaLocationHint or SchemaURL to be the logical location of the XML Schema, not the namespace or the actual location of the XML Schema in the XDB repository. The one advantage of using the actual location in the XML DB repository iss that it allows 3rd party tools like XMLSPY to locate the XML schema.
Eg
begin
dbms_xmlschema.registerSchema(schemaurl=>'http://www.gimo-armada.es/ORSWE/xsd/ICRI/ICR.xsd', schemadoc=>xdburitype('/ORSWE/Esquemas/ICRI/ICR.xsd').getXML(), local=>FALSE, gentypes=>TRUE, genbean=>FALSE, gentables=>TRUE, force=>FALSE, owner=>'DAVID');
end;
/At this point the value of the schemaLocation tag is a tuple consisting of the targetNamespace and the SchemaLocationHint
eg
<ICR xmlns="http://www.gimo-armada.es/ORSWE/ICRI"
xmlns:xdb="http://xmlns.oracle.com/xdb"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.gimo-armada.es/ORSWE/ICRI
http://www.gimo-armada.es/ORSWE/xsd/ICRI/ICR.xsd">hope this helps..
