<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Dear all,</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I am working on the update of the Extended Procedures book.</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">One of the things agreed during the last meeting was to describe better the various possibilities of the TLV format. One of the items to be addressed in nested procedures. i.e. putting another
TLV inside the value field. While I have no problem adding this to the spec, I am wondering if there is a use case for this in the scope of the Extended Procedures. Looking at the various proposed procedures, I could not find any.</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif""><br>
So if there is no use case for nesting in the scope of the book, do we really need to specify it?</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Cheers,<br>
Daniel</span> <br>
