Removing an XML Schema through Enterprise Manager

Question

Hi all,
I have created an XML schema using the Enterprise Manager. But the problem is that I can't remove it. When I use the menu option to remove the XML Schema, I get the following error:
VBO-8051: XML Schema cannot be dropped.
ORA-31000:Resource [User].[SchemaName] is not an XDB document
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 0
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 80
ORA-06512: at line 1
If anyone has any thoughts they would be greatly appreciated.
Thank you,
Mike

What was the URL used to register the schema. Is this the same URL that was passed to delete schema. You can check the list of registered schemas with the following query
SQL> desc user_xml_schemas
Name Null? Type
SCHEMA_URL VARCHAR2(700)
LOCAL VARCHAR2(3)
SCHEMA SYS.XMLTYPE(XMLSchema "http:
//xmlns.oracle.com/xdb/XDBSc
hema.xsd" Element "schema")
INT_OBJNAME VARCHAR2(4000)
QUAL_SCHEMA_URL VARCHAR2(2839)
SQL> select schema_url from user_xml_schemas
2 /
SCHEMA_URL
http://localhost:8080/home/SCOTT/xsd/purchaseOrder.xsd
