title: Transform an int to a char
body: <p>I'd like to write the alphabet with a link for each letter. So I used templates but I don't how to make this letter I tried that but I had a normal mistake : (A decimal representation must imediately follow the &amp;# in a character reference).</p>
  
  <pre><code>&lt;xsl:template name="alphabet"&gt;
      &lt;xsl:param name="iLetter"/&gt;
      &lt;xsl:if test="$iLetter &amp;lt; 91"&gt;
          &lt;a&gt;&lt;xsl:attribute name="href"&gt;req.html?X_letter=&amp;#&lt;xsl:value-of select="$iLetter"/&gt;;&lt;/xsl:attribute&gt;&amp;#&lt;xsl:value-of select="$iLetter"/&gt;;&lt;/xsl:attribute&gt;&lt;/a&gt;
          &lt;xsl:call-template name="alphabet"&gt;
              &lt;xsl:with-param name="iLetter" select="number($iLetter)+1"/&gt;
          &lt;/xsl:call-template&gt;
      &lt;/xsl:if&gt;
  &lt;/xsl:template&gt;
  </code></pre>
  
  <p>And I call this template ilke that:</p>
  
  <pre><code>&lt;xsl:call-template name="alphabet"&gt;
          &lt;xsl:with-param name="iLetter" select="number(65)"/&gt;
  &lt;/xsl:call-template&gt;
  </code></pre>
  
  <p>So, I'd like to obtain this result:</p>
  
  <p><code>A B C D ..... X Y Z</code> without ... of course :)</p>
