<span style=" font-size:10pt;font-family:sans-serif">Dear All,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">please find attached
an input from the chair, compiled from a number of inputs received
over a couple of years from WG members and external readers.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Many thanks to
Gunther and Wai for helping me with the revision of the green book.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I trust you will
be able to read it before the Spring 2021 meeting (remote or physical)
so as to adopt the changes and proceed with the request for publication
in 2021. </span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Should you have
additional comments or change requests also for other parts of the green
book, please send your input at least 2 weeks before the current official
start date of the meeting.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Best Regards,
Enrico</span>
