Before this fix, the namespaces element were wrongly nested.

summary: Prototype MAM summary

This is a prototype for an experimental archive summary API recently
added in [Prosody trunk](https://hg.prosody.im/trunk/rev/2c5546cc5c70).
# Protocol
::: {.alert .alert-danger}
This is not a finished protocol, but a prototype meant for testing.

A basic query:
``` {.xml}
<iq id="lx7" type="get">
<summary xmlns="xmpp:prosody.im/mod_map"/>
</iq>
```
Answered like:
``` {.xml}
<iq type="result" id="lx7">
<summary xmlns="xmpp:prosody.im/mod_map">
<item jid="juliet@capulet.lit">
<count>3</count>
<start>2019-02-25T15:48:00+0100</start>
<end>2019-08-23T01:39:50+02:00</end>
<body>O Romeo, Romeo! wherefore art thou Romeo?</body>
</item>
</summary>
</iq>
```
It can also take dataform and RSM parameters similar to a [filtered MAM
query](https://xmpp.org/extensions/xep-0313.html#filter).
E.g if the last message you received had an id `09af3-cc343-b409f` then
the following query would tell you who sent you messages since:
``` {.xml}
<iq id="lx8" type="get">
<summary xmlns="xmpp:prosody.im/mod_map">
<set xmlns="http://jabber.org/protocol/rsm">
<max>10</max>
<after>09af3-cc343-b409f</after>
</set>
</summary>
</iq>
```
