  35 <ul>
  36   <li>Values of integer type shall be <a href="#double_quotation">denoted by one or more digits</a>; the first digit shall not be zero unless the value is 0.</li>
  37   <li>The value zero shall be represented by a single zero.</li>
  38   <li>The <a href="#quotation_inside">range of the permitted integer values</a> may be specified.</li>
  39   <li>The specified <a href="infinity.html#double_quotation">range may be infinite</a> (both positive and negative; see the keyword <a href="infinity.html"><b><font
