I could not understand why so many namespaces are used in 'jabber' Server Architecture. Does this help in optimising the parsing of XML Document? If it does, then how? Is there any  other motivation for keeping so many namespaces? I am new to XML and not very comfortable with namespaces.</FONT></DIV> <DIV> </DIV> <DIV><FONT face=Arial size=2>Thanks and Regards,</FONT></DIV> <DIV><FONT face=Arial size=2>Hitesh.</FONT></DIV> <DIV> </DIV></BLOCKQUOTE></BODY></HTML>
