Views for XML with attributes using XMlTable

I created an XMLType table

CREATE TABLE PERSON OF XMLType
  XMLTYPE store AS OBJECT RELATIONAL
  XMLSCHEMA "PERSON.XSD" ELEMENT "root";

The XML is -

<root>
<Person empid="1" empname="Joe" empproj="IT" emporg="Consulting" />
</root>

I created view for the XMLType table. But I could not see the values inserted in table in the view. I want to have the XML attributes (empid, empname, empproj, emporg) as columns of VIEW person_master_view for table PERSON.

CREATE OR REPLACE VIEW
  person_master_view(empid, empname, empproj, emporg)
AS SELECT xt.*
     FROM PERSON,
                XMLTable ('/root/Person' passing PERSON.object_value
                                 columns
                                     empid        number(10)   path '/Person',
                                     empname      varchar2(30) path '/Person',
                                     empproj      varchar2(30) path '/Person',
                                     emporg       varchar2(30) path '/Person'
                             ) as xt
