<p>A node owner may want to edit the list of subscriptions associated with a given node. Support for this feature ("pubsub#manage-subscriptions") is OPTIONAL.</p>

<section3 topic='Request' anchor='owner-subscriptions-request'>
<p>In order to request a list of all subscriptions, a node owner MUST send a subscriptions request, consisting of a &lt;subscriptions/&gt; element whose 'node' attribute specifies the NodeID of the relevant node.</p>
