           A Path Element represents a hop in the path a message has taken
           through the network.
           An ordered list of Path Elements may be appended to any routed
           <tt>PutMessage</tt>s or <tt>ResultMessage</tt>s.
-          A Path Element identifies a peer on the path.
-          The Path Element is signed by the next peer on the path after
-         the next peer made its routing decision.
-          This signature is also part of the Path Element along with the
-          Peer ID of the previous peer.
+          The signature of a Path Element is created by the current hop
+          after it made its routing decision identifiying the successor peer.
         </t>
         <t>
-          The public key of the peer which created the signature is in the
-          next path element, or is the sender of the message if this was the
-          last path element.
+          A path may be truncated in which case the signature of the truncated
+          Path Element is omitted leaving only the Peer ID required for the
+          verification of the subsequent Path Element signature.
+          Such a truncated path is indicated with the respective flag.
+          The Peer ID of the last Path Element is omitted as it must be that of
+          the sender of the PutMesssage or ResultMessage.
           The wire format of a Path Element is illustrated in
           <xref target="figure_pathelement"/>.
