"""
XMPP's <message> stanzas are a "push" mechanism to send information
to other XMPP entities without requiring a response.
Chat clients will typically use <message> stanzas that have a type
of either "chat" or "groupchat".
When handling a message event, be sure to check if the message is
an error response.
Example <message> stanzas:
<message to="user1@example.com" from="user2@example.com">
<body>Hi!</body>
</message>
<message type="groupchat" to="room@conference.example.com">
<body>Hi everyone!</body>
</message>
Stanza Interface:
body -- The main contents of the message.
subject -- An optional description of the message's contents.
mucroom -- (Read-only) The name of the MUC room that sent the message.
mucnick -- (Read-only) The MUC nickname of message's sender.
Attributes:
types -- May be one of: normal, chat, headline, groupchat, or error.
Methods:
setup -- Overrides StanzaBase.setup.
chat -- Set the message type to 'chat'.
normal -- Set the message type to 'normal'.
reply -- Overrides StanzaBase.reply
get_type -- Overrides StanzaBase interface
get_mucroom -- Return the name of the MUC room of the message.
set_mucroom -- Dummy method to prevent assignment.
del_mucroom -- Dummy method to prevent deletion.
get_mucnick -- Return the MUC nickname of the message's sender.
set_mucnick -- Dummy method to prevent assignment.
del_mucnick -- Dummy method to prevent deletion.
