--I just realized that we probably don't need the Namespace element of this. The description of this would read something like what they say in 29.171:
--"This IE contains a UTF-8 encoded PIDF-LO XML document as defined in IETF RFC 4119 [13].
--The document shall only contain a civic address using the namespaces
--"urn:ietf:params:xml:ns:pidf:geopriv10:civicAddr" per IETF RFC 5139 [14] and
--"urn:ietf:params:xml:ns:pidf:geopriv10:civicAddr:ext" per IETF RFC 6848 [15].
