title: Why did Technical Corrigendum 2 to ISO/IEC 13211-1:1995 omit "bar" from the "token" rule?
body: <p><em>Cor.2</em> says (only) the following about clause 6.4:</p>
  
  <blockquote>
    <h2>6.4 Tokens</h2>
    
    <p><em>Add as the last syntax rule:</em></p>
  
  <pre><code>bar (* 6.4 *)
     = [ layout text sequence (* 6.4.1 *) ] ,
       bar token (* 6.4.8 *) ;
  </code></pre>
  </blockquote>
  
  <p>Surely another modification to 6.4 is intended, namely to add <code>bar (* 6.4 *)</code> to the definition of <code>token (* 6.4 *)</code>, which is as follows in <em>ISO/IEC 13211-1:1995</em>:</p>
  
  <blockquote>
  <pre><code>token (* 6.4 *)
     = name (* 6.4 *)
     | variable (* 6.4 *)
     | integer (* 6.4 *)
     | float number (* 6.4 *)
     | double quoted list (* 6.4 *)
     | open (* 6.4 *)
     | open ct (* 6.4 *)
     | close (* 6.4 *)
     | open list (* 6.4 *)
     | close list (* 6.4 *)
     | open curly (* 6.4 *)
     | close curly (* 6.4 *)
     | ht sep (* 6.4 *)
     | comma (* 6.4 *)
     ;
  </code></pre>
  </blockquote>
  
  <p>Is this a minor omission from <em>Cor.2</em> or have I misunderstood?</p>
