- A user MAY subsequently modify subscription to nodes in a channel by sending a subscription modification request encoded as a <update-subscription/$gt; child element of <iq/> element. The <update-subscription/$gt; element is qualified by the 'urn:xmpp:mix:1' namespace. The requested notes are encoded as <subscribe/> child elements of the <update-subscription/$gt; element with the node name encoded as a 'node' attribute. This modification goes directly from client to MIX channel, as this change does not impact the roster and so does not need any local action. The following example shows subscription modification. + A user MAY subsequently modify subscription to nodes in a channel by sending a subscription modification request encoded as a <update-subscription/> child element of <iq/> element.

- It can also be useful to share some or all of the messages from the 1:1 discussion into the new channel. The mechanism to do this is to forward messages to be shared in the MUC using &xep0297;. A body SHOULD NOT be used in the outer message. - Sharing history is optional. If history is shared, it MUST be done by the user creating the channel before the other user is invited. Any other use of forwarded messages MUST be treated as a member of the MUC forwarding a message to the channel and MUST NOT be treated as history sharing. + It can also be useful to share some or all of the messages from the 1:1 discussion into the new channel.

- There are a number of security considerations with use of MUC history. There may be sensitive information in the 1:1 MUC history, and the user sharing this history should ensure that none of this is sensitive, prior to sharing in this way. The user creating the MUC has potential to inject history messages which were not part of the history. It is recommended that the second user joining the MUC to validate that the messages match the history and to take appropriate action if they do not. + There are a number of security considerations with sharing 1:1 history in a channel.
