How do I use SelectSingleNode to identify the id and link nodes in the XML below:

The following code works for the playlist node but not the id and link nodes:
XmlDocument doc = new XmlDocument();
            XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
            nsmgr.AddNamespace("pl", @"http://bbc.co.uk/2008/emp/playlist");
 
            doc.SelectSingleNode("//pl:playlist", nsmgr)  // is OK
            doc.SelectSingleNode("//pl:playlist/id", nsmgr)  // returns null
            doc.SelectSingleNode("//pl:playlist/link", nsmgr)  // returns null
            
 
<?xml version="1.0" encoding="UTF-8"?>
<playlist xmlns="http://bbc.co.uk/2008/emp/playlist" revision="1">
	<id>tag:bbc.co.uk,2008:pips:b00gp3j1:playlist</id>
	<link rel="self" href="http://www.bbc.co.uk/iplayer/playlist/b00gp3j1"/>	
</playlist>
