I haven&#x27;t done any research or anything, but I can&#x27;t imagine any reasonable person interpreting &quot;shall&quot; to mean &quot;can&quot;, &quot;might&quot;, &quot;may&quot;, or &quot;is allowed to&quot;.<p>Shall means &quot;will&quot; or &quot;must&quot;.  Like any uncommon word I&#x27;m sure it&#x27;s frequently used incorrectly, and I recognize that language evolves, but I have difficulty believing those other uses have become prevalent enough to be considered valid.
