  <!-- * About the $info param used in this stylesheet -->
  <!-- * -->
  <!-- * The $info param is a "master info" node set that contains -->
  <!-- * the entire contents of the *info child of the current -->
  <!-- * Refentry, plus the entire contents of the *info children of -->
  <!-- * all ancestors of the current Refentry, in document order. -->
  <!-- * -->
  <!-- * We try to find a "best match" for selecting content from -->
  <!-- * $infor; we look through it in reverse document order until we -->
  <!-- * can find something usable. -->
  <!-- * -->
  <!-- * Specifically what the basic metadata-gathering XPath expression -->
  <!-- * in this stylesheet does is: -->
  <!-- * -->
  <!-- *   1. Look through the entire "master info" node set.-->
  <!-- *   2. Get the last node in the set that contains, for -->
  <!-- *      example, an Author element. That amounts to being the -->
  <!-- *      closest *info node to the Refentry - either its *info -->
  <!-- *      child, or the *info node of its closest ancestor that -->
  <!-- *      contains an Author. -->

  <!-- ================================================================== -->
  <!-- * Get user "refentry metadata" preferences -->
  <!-- ================================================================== -->
  <!-- * The DocBook XSL stylesheets include several user-configurable -->
  <!-- * global stylesheet parameters for controlling refentry metadata -->
  <!-- * gathering. Those parameters are not read directly by the other -->
  <!-- * refentry metadata-gathering templates. Instead, they are read -->
  <!-- * only by the get.refentry.metadata.prefs template, which -->
  <!-- * assembles them into a structure that is then passed to the -->
  <!-- * other refentry metadata-gathering template. -->
