  <mainDescription>&lt;p> The items in this checklist represent good practices for creating and communicating &#xD;
  a robust architecture. It may not be possible to address every item, and you &#xD;
  may be able to address some items to only a limited extent. In these cases, &#xD;
  be sure that there are good reasons for only partially addressing an item or &#xD;
  not addressing an item at all. &lt;/p>&#xD;
&lt;p> Architectural revisions can occur every day. Use this checklist regularly &#xD;
  to ensure that the results are robust, consistent, and understandable. Make &#xD;
  the architecture good enough for the specific goals being addressed by using &#xD;
  this checklist to identify areas that have been skipped, ignored, or not sufficiently &#xD;
  addressed. &lt;/p></mainDescription>
