<P><FONT SIZE=2>I would like to know from George if he believes</FONT>
<BR><FONT SIZE=2>5.5.2 is irrelevant, or simply ambiguously worded.</FONT>
<BR><FONT SIZE=2>I believe (and I suspect that George may concur)</FONT>
<BR><FONT SIZE=2>that error protection for the context is</FONT>
<BR><FONT SIZE=2>required (consider the possible impact of attempting</FONT>
<BR><FONT SIZE=2>to install or use erroneous context at an AR), and </FONT>
<BR><FONT SIZE=2>that it is important to clearly identify that requirement </FONT>
<BR><FONT SIZE=2>(particularly given that there are no transport </FONT>
<BR><FONT SIZE=2>requirements in the id).</FONT>

&amp;lt;BR&amp;gt;&amp;lt;FONT SIZE=2&amp;gt;&amp;amp;gt; 4.12 The context information to be transferred MUST be &amp;lt;/FONT&amp;gt;

&amp;lt;BR&amp;gt;&amp;lt;FONT SIZE=2&amp;gt;&amp;amp;gt; 4.13 The context transfer solution WILL NOT verify the context&amp;lt;/FONT&amp;gt;
&amp;lt;BR&amp;gt;&amp;lt;FONT SIZE=2&amp;gt;&amp;amp;gt; information prior to transfer.&amp;lt;/FONT&amp;gt;
&amp;lt;BR&amp;gt;&amp;lt;FONT SIZE=2&amp;gt;&amp;amp;gt; 4.15 The context transfer solution MAY include methods for &amp;lt;/FONT&amp;gt;

&amp;lt;BR&amp;gt;&amp;lt;FONT SIZE=2&amp;gt;&amp;amp;gt; with non-IETF mobility solutions.&amp;lt;/FONT&amp;gt;
