      Solution to problem where incoming collection description contains HTML and we want to preserve

  <!-- preserve any HTML tags *within* the collection description
       Why is this adding an xmlns namespace to the first HTML tag encountered and converting
       non html entities like the apostrophe character into their entity forms?
       This seems to assume entities in the input should be converted:
       https://stackoverflow.com/questions/31517944/xsl-disable-output-escaping-copy-of
       But I'm wondering why when there's no entity in the input, copy-of produces entities
       for chars like apostrophe in the output?
       Note: there's xsl:copy and xsl:copy-of, we want copy-of!
