title: xsl:value-of is adding white space
body: <p>I have XSLT like:</p>
  
  <pre><code>&lt;xsl:variable name="letter"&gt;
    &lt;xsl:value-of select="@display_value"/&gt;
  &lt;/xsl:variable&gt;
  </code></pre>
  
  <p>and somewhere I use:</p>
  
  <pre><code>&lt;xsl:value-of select="$letter"/&gt;  
  </code></pre>
  
  <p>But this is adding extra space.  I'd like to use <code>xsl:text</code>, but it doesn't take a variable.</p>
  
  <p>Do you have suggestions, please, on how to get rid of the space?</p>
