     <p>If a service implements a hierarchy of nodes (by means of <link url='#collections'>Collection Nodes</link>), it MUST also enable entities to discover the nodes in that hierarchy by means of the <strong>Service Discovery</strong> protocol, subject to the recommendations in <cite>XEP-0030</cite> regarding large result sets (for which &xep0055; or some other protocol SHOULD be used). The following examples show the use of service discovery in discovering the nodes available at a hierarchical pubsub service.</p>
     <p>Note: Node hierarchies and collection nodes are OPTIONAL. For details, refer to the <link url='#impl-semantics'>NodeID Semantics</link> and <link url='#collections'>Collection Nodes</link> sections of this document.</p>
-    <p>The service SHOULD return a full list of the public nodes it hosts (i.e., not return any nodes that don't contain the "http://jabber.org/protocol/pubsub#public" feature or that have the feature set to false).</p>
     <p>In the first example, an entity sends a service discovery items ("disco#items") request to the root node (i.e., the service itself), which is a <link url='#collections'>Collection Node</link>:</p>
