     <p>The root element for geolocation data is &lt;geoloc/&gt; as defined in &xep0080;. The information is structured by means of a &lt;geoloc /> element that is qualified by the 'http://jabber.org/protocol/geoloc' namespace. The &lt;geoloc/&gt; element MUST be contained within a &lt;field/&gt; element qualified by the 'jabber:x:data' namespace.</p>
     <p>The following example is provided only for the purpose of illustration; consult the specifications for using protocols (e.g., &xep0080;) to see canonical examples.</p>

     <p>It is imperative to control access to location information, at least by default. Imagine that a stalker got unauthorized access to this information, with enough accuracy and timeliness to be able to find the target person. This scenario could lead to loss of life, so please take access control checks seriously. If an error is deliberately added to a location, the error SHOULD be the same for all receivers, to minimize the likelihood of triangulation. In the case of deliberate error, the &lt;accuracy /> element SHOULD NOT be included.</p>
