title: NSIS xml::SaveFile removes xml-stylesheet declaration
body: <p>I am using this plugin <a href="https://nsis.sourceforge.io/XML_plug-in" rel="nofollow noreferrer">https://nsis.sourceforge.io/XML_plug-in</a>. However, I found out after <code>xml::SaveFile</code>, <code>xml-stylesheet</code> is removed from the xml.
  <code>&lt;?xml-stylesheet type=&quot;text/xsl&quot; href=&quot;HHConfig.xslt&quot;?&gt;</code> to <code>&lt;?xml ?&gt;</code>.</p>
  <p>I am looking for the solution in internet. However, I only found this:

  <p>Don't remove &quot;xml-stylesheet&quot; declaration</p>
