RE: Error in definition of head element

Thanks for the explanation. However, if the following is correct

<!ELEMENT head (%head.misc;,
     ((title, %head.misc;, (base, %head.misc;)?) |
      (base, %head.misc;, (title, %head.misc;))))>

aren't the parentheses redundant in "(title, %head.misc;)"?

Best regards,
Dave Meredith
