If a client implements message reactions, it MUST specify the
'urn:xmpp:reactions:0' feature in its service discovery information features
as specified in &xep0030; and the Entity Capabilities profile specified in &xep0115;.

<p>
In some cases, only a limited number and/or subset
of emojis are allowed to react to a message.
This is particularly useful in the context of gateways to other chat
networks that are not as permissive about which and how many emojis
can be used for message reactions.
MUC components may also allow room admins to restrict the subset and/or number
of emojis per message.
</p>
<p>
To allow clients to adapt their UIs, entities that have such restrictions in place
SHOULD advertise it with &xep0128; in a &xep0004; using the
'urn:xmpp:reactions:0:restrictions' namespace as FORM_TYPE.

In some cases, only a limited number and/or subset
of emojis are allowed to react to a message.
This is particularly useful in the context of gateways to other chat
networks that are not as permissive about which and how many emojis
can be used for message reactions.
MUC components may also allow room admins to restrict the subset and/or number
of emojis per message.
Entities implementing reaction restrictions MUST reply to invalid reactions payloads
with a message type="error" containing a 'not-acceptable' error.
The error payload SHOULD contain a human-readable text message explaining the reaction rules.

<p>
When receiving this kind of error message, the reaction-sending entity MUST consider that its emoji reactions
to this message are now void.
</p>
<p>
Optionally, an error message can contain a reactions element, listing the subset of emojis that were valid in
the original reactions message.

<example caption="Romeo removes a subset of reactions"><![CDATA[
<message from="romeo@legacy-love-network.capulet.net"

<reactions id='restricted-reactions-1' xmlns='urn:xmpp:reactions:0'>
<reaction>💘</reaction>
</reactions>
</error>
</message>]]></example>
<p>
In this case, the reaction-sending entity MUST modify the emojis accordingly.
When receiving this error message, the reaction-sending entity MUST revert the "message reactions"
to its previous state in its user interface.
