These stanzas are used to store disco         information in memory without any additional processing.          Arguments:             xmpp -- The main SleekXMPP object. Create a new set of stanzas for the provided         JID and node combination.          Arguments:             jid  -- The JID that will own the new stanzas.             node -- The node that will own the new stanzas. # ================================================================= # Node Handlers # # Each handler accepts three arguments: jid, node, and data. # The jid and node parameters together determine the set of # info and items stanzas that will be retrieved or added. # The data parameter is a dictionary with additional paramters # that will be passed to other calls. Return the stored info data for the requested JID/node combination.          The data parameter is not used. Reset the info stanza for a given JID/node combination.          The data parameter is not used. Return the stored items data for the requested JID/node combination.          The data parameter is not used. Replace the stored items data for a JID/node combination.          The data parameter is not used. Reset the items stanza for a given JID/node combination.          The data parameter is not used. Add a new identity to te JID/node combination.          The data parameter may provide:             category -- The general category to which the agent belongs.             itype    -- A more specific designation with the category.             name     -- Optional human readable name for this identity.             lang     -- Optional standard xml:lang value. Add or replace all identities for a JID/node combination.          The data parameter should include:             identities -- A list of identities in tuple form:                             (category, type, name, lang) Remove an identity from a JID/node combination.          The data parameter may provide:             category -- The general category to which the agent belonged.             itype    -- A more specific designation with the category.             name     -- Optional human readable name for this identity.             lang     -- Optional, standard xml:lang value. Remove all identities from a JID/node combination.          The data parameter is not used. Add a feature to a JID/node combination.          The data parameter should include:             feature -- The namespace of the supported feature. Add or replace all features for a JID/node combination.          The data parameter should include:             features -- The new set of supported features. Remove a feature from a JID/node combination.          The data parameter should include:             feature -- The namespace of the removed feature. Remove all features from a JID/node combination.          The data parameter is not used. Add an item to a JID/node combination.          The data parameter may include:             ijid  -- The JID for the item.             inode -- Optional additional information to reference                      non-addressable items.             name  -- Optional human readable name for the item. Remove an item from a JID/node combination.          The data parameter may include:             ijid  -- JID of the item to remove.             inode -- Optional extra identifying information.
