Manages private data, which is a mechanism to allow users to store arbitrary XML data on an XMPP server. Each private data chunk is defined by a element name and XML namespace. Example private data:
<color xmlns="http://example.com/xmpp/color"> <favorite>blue</blue> <leastFavorite>puce</leastFavorite> </color>
