Renamed to User Location; corrected pubsub examples; removed non-pubsub examples; added uri element.
Renamed to User Location; corrected pubsub examples; recommended pubsub/PEP as transport for location information about human users; added uri element.
NOTE: The datatypes specified above are defined in &w3xmlschema2;.
-Location information SHOULD be communicated and transported by means of &xep0060; or the subset thereof specified in &xep0163; (the examples below assume that the user's XMPP server supports PEP, thus the publish request lacks a 'to' address and the notification message has a 'from' address of the user's bare JID).
-Because location information is not pure presence information and can change independently of the user's availability, it SHOULD NOT be provided as an extension to &PRESENCE;.
+Location information about human users SHOULD be communicated and transported by means of &xep0060; or the subset thereof specified in &xep0163; (the examples below assume that the user's XMPP server supports PEP, thus the publish request lacks a 'to' address and the notification message has a 'from' address of the user's bare JID).
+Although the XMPP publish-subscribe extension is the preferred means for transporting location information about human users, applications that do not involve human users (e.g., device tracking) MAY use other transport methods; however, because location information is not pure presence information and can change independently of network availability, it SHOULD NOT be provided as an extension to &PRESENCE;.
