| <p>This section extends <link url="https://xmpp.org/extensions/xep-0384.html#message-structure-description">the corresponding section in XEP-0384</link>. Three new attributes are introduced, otherwise the structure is untouched. Clients that don't support this specification should ignore the (for them) unknown attributes, resulting in seamless compatibility. The data needed to fill the new attributes is explained below the updated example.</p> | ||
| <p>The <keys> element is extended to also have an attribute called 'dhcs_sig' containing the base64 encoded signature of the Diffie-Hellman ratchet counters.</p> | ||
| <p>The <key> element is extended to also have two attributes called 'dhc' (holding an unsigneed integer) and 'ekid' (holding base64 encoded data).</p> | ||
| <p>The <link url="https://xmpp.org/extensions/xep-0384.html#example-7">example</link> is updated to include the newly introduced attributes:</p><!-- TODO: Anchor for the example --> |

Initially planned to go into XEP-0384 directly, it seemed like a better idea to move automatic session healing into its own XEP and make it fully optional for OMEMO.
The rendered version can be found here.
Depends on version 0.7 of OMEMO, the PR for which is here.
