  https://www.balisage.net/Proceedings/vol25/html/Galtman01/BalisageVol25-Galtman01.html
  
  In short: the internal design of XSpec forces kludges when one wants to use xsl:result-document in their stylesheets. But I don't
  want to be strangled by kludges at the beginning of work, I've already lost quite a bit of time on this investigation,
  I will therefore "just code" and then can think of externalizing bits of templates if we want to play with tests. For now,
  I don't want to have to handle context items is a special way inside variables, etc., because I'm not sure it's worth it.
