             Specifying Civic Address Extensions in PIDF-LO
                   draft-ietf-geopriv-local-civic-04

Abstract

   New fields are occasionally added to civic addresses.  A backwardly-
   compatible mechanism for adding civic address elements to the Geopriv
   civic address format is described.  A formal mechanism for handling
   unsupported extensions when translating between XML and DHCP civic
   address forms is defined for entities that need to perform this
   translation.  Intial extensions for some new elements are also
   defined.  The LoST protocol mechanism that returns civic address
   element names used for validation of location information is
   clarified to require a namespace on each element.
