Views for XML with attributes using XMlTable
The following worked -    

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