title: XSLT: Define a param with & ampersand
body: <p>I need to define a <code>xsl:param</code> with a string that contains <code>&amp;</code> character for further processing. 
  For example:</p>
  
  <pre><code>&lt;xsl:param name="greeting" as="xs:string"&gt;Hi &amp; Bye&lt;/xsl:param&gt;
  </code></pre>
  
  <p>Important Notice: 
  I am using a xslt converter component in a webservice tool. What I do, is that I just initialize the <code>param</code> and as the webservice is called the <code>param</code> is set to a value of a variable which was set in previous steps. So I have no control on the string, i.e meaning I can't use <code>&amp;amp;</code></p>
  
  <p>Any ideas how to do that?</p>
  
  <p>Thanks in advance.</p>
