  XSLTProcessor in Edge browser inserts xmlns="http://www.w3.org/1999/xhtml" in XML document on elements <form>, <table> and <button> even though default namespace of XML document is not XHTML.

  Javascript:

  var processor = new XSLTProcessor()
  processor.importStylesheet(xsl);
  var el = processor.transformToDocument(xml);

  Both 'xsl' and 'xml' objects are XML documents loaded via XMLHTTPRequest.responseXML.

  XML passed into transformation:

  <dataset>
      <form>
          <group>
              <button></button>
          </group>
      </form>
  </dataset>

  XML returned from transformation as 'el':

  <dataset>
      <form xmlns="http://www.w3.org/1999/xhtml">
          <group xmlns="">
              <button xmlns="http://www.w3.org/1999/xhtml"></button>
          </group>
      </form>
  </dataset>

  XSL:

  <?xml version='1.0'?>
  <xsl:stylesheet version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
  <xsl:output method="xml" omit-xml-declaration="yes"/>
  
  <xsl:template match="@* | * | comment()" priority="-2">
  <xsl:copy>
  <xsl:apply-templates select="@* | * | text() | comment()"/>
  </xsl:copy>
  </xsl:template>
  </xsl:stylesheet>

  Subsequent transformations on this XML fail as these nodes have an incorrect namespace.

  This transformation logic works correctly in Internet Explorer, and Firefox and Chrome.
