XML SCHEMA registration for XML TYPE (storing XML files in Oracle 10g)

Question

I have created the XML Schema for the XML file stored in Oracle 10g and also added this Schema into the database. I have related that schema with the column in the table which contains the XML file. When i execute the query to fetch the data from the stored file i am getting a blank resultset. Is registering the XML Schema is necessary, if yes then please let me know the process of doing it. I have tried following steps to register Schema, but it is not working
Step1:
DECLARE
v_return BOOLEAN;
BEGIN
v_return := dbms_xdb.createFolder('/home/');
v_return := dbms_xdb.createFolder('/home/DEV/');
v_return := dbms_xdb.createFolder('/home/DEV/xsd/');
v_return := dbms_xdb.createFolder('/home/DEV/messages/');
v_return := dbms_xdb.createFolder('/home/DEV/employees/');
COMMIT;
END;
STEP 2:
Connecting To XML DB
Step3:
Register XML schema
I am failing to execute step number 2 and hence not able to register the schema also.
