<p>Just like with the public key data node, in absence of a use-case specific access model,
it is RECOMMENDED to set the access model of the metadata node to 'open', such that entities
without mutual presence subscription are still able to access the node items.</p>
<p> The ID of the metadata node is 'urn:xmpp:openpgp:0:public-keys'. It contains a
