Am not matching urn:service:sos ... in my element ... which parameter does this belongs to

The hmr needs to change  <urn:service:sos@psap-co-911.bvcog.911.test.gov:5060;lr>  to          <sip:911@psap-co-911.bvcog.911.test.gov:5060>. The the uri elements don't match. What is wrong with my approach ?
