title: Including an XML file in an XML/XSL file
body: <p>So currently I'm doing some XML-> XSLT-> (HTML5/CSS3) work. Right now I have a menu.xml file, and I'd like to include it in either the XSL file or the XML page. I've done lots of searching, but I'm unable to find a straightforward answer.</p>
  
  <p>So, how do I include an XML file in to another XML file or in to a XSL file?</p>
  
  <p>Edit: By include, I mean referencing/loading it from another file, not copy and pasting it or simply embedding it.</p>
