title: XSLT conditional include of external file
body: <p>I want to perform a conditional include in XSLT, but xsl:include is a top level element. You can only use xsl:if or xsl:choose inside of a template. Is there any kind of hack or work around which allows a conditional include of an external file? I tried to use the document() function, but it fails to load my external file ( probably because it doesn't conform to some set of rules which would make it "valid" ). </p>
  
  <p>My external xml file is a bunch of xslt code fragments. depending on the value of a variable in the main XSLT file, the corisponding code from the external file should be "copy/pasted" in place ( like conditional include in C or PHP ).</p>
  
  <p>The flow of my main XSLT file should proceed in the following manner:</p>
  
  <pre><code>$configurationMode
  if ( $configurationMode = Standard ) { xsl:include="standard.xml" } else { xsl:include="alt.xml" }
  </code></pre>
  
  <p>Obviously I cannot do it as simply as the above, hence why I am asking if there is a hack or workaround. </p>
