-        There MUST always be at least one Owner for a Channel.   Owners, Administrators, Participants, and Allowed are optional and do not need to be set.  Where no owner is explicitly set, it is anticipated that a server administrator will have owner rights.   Rights are defined in a strictly hierarchical manner following the order of this table, so that for example Owners will always have rights that Administrators have.

+        When a channel is created with default parameters, the Owner in the configuration is set to the JID that creates the channel.  Where parameters are included, the Owner or Owners MUST be specified explicitly.  If an owner is specified that is not the JID creating the channel, the owner is recommended to verify that this user accepts the responsibility of being an owner of this channel.   Protocol to support this verification may be specified in a future XEP.  Note that the 'Last Change Made By' in configuration node MUST be set to the JID that creates the channel.
