<p>It is expected that clients will not send message corrections to clients that do not support them, as non-supporting clients will render these as duplicate (corrected) messages. There may be environments (particularly within a &xep0045; MUC room) where it is unknown whether some or all recipients support this extension, and implementors could choose to allow or disallow sending in such cases, as is appropriate for the intended deployments. It is suggested that when the support of recipients is not known a sending client will make the user aware of the potential for duplicate messages to be interpreted by the recipients.</p>
<p>Message corrections sent to clients that do not support them will be rendered as duplicate (corrected) messages. In most Instant Messaging environments (particularly within a &xep0045; room, but also with a recipient having multiple clients using &xep0280; and &xep0313;) it is unknown whether some or all receiving devices support this extension. It is suggested that a client should always allow sending corrections, but may make the user aware of the potential for duplicate messages to be interpreted by the recipients. In restricted environments, implementors could choose to allow or disallow sending in such cases, as is appropriate for the intended deployments.</p>

<section1 topic='Use Case' anchor='usecase'>
<p>When a user indicates to the client that he wants to correct the most recently sent message to a contact, the client will resend the corrected message with a new id, and with the replace payload refering to the previous message by id. The receiving client then treats the newly received payloads as completely replacing all payloads of the original message.</p>
