<html> Hi, I'm just curious about the usage of jabber:x:signed namespace.  Exactly what is being signed?  The entire presence message or just the data contained?  And if it's just the data contained, then does this include the XML elements or only the data inside... Using the example in the protocol.html, here's the <presence>: <presence from='juliet@capulet.com/balcony' to='romeo@montague.net/orchard'>   <show>away</show>   <status>be back later</status>   <x xmlns='jabber:x:signed'>   iD8DBQA6kasv0xpc2/POfPkRAnz0AJ9UEYYWWSReddIKk3AYMfTFtqQDJwCfbcLd   JcSUOR0FlS+rDFjAPaSMgSM+iNaNm   </x> </presence> Here, does the signed message sign the entire <presence> xml block (including the presence tag, but excluding the <x> signed tag)?  Or does it only sign the "<show>away</show><status>be back later</status>"???  Or does it sign just the data "away be back later"??? I assume the second one is the most reasonable one since the <presence> changes and is altered. Also is there any other occasion in which the jabber:x:signed namespace can be used other than in the <presence> tag? The jabber:x:encrypted makes much more sense while jabber:x:signed doesn't make much sense at all... Chris <x-sigsep></x-sigsep> PGP at ldap://certserver.pgp.com/ </html>
