Ok, that's a better explanation than the spec has.  But I still think
the requirement to use at least SpecialCasing.txt needs to be clearer.

New wording, v2:

  If and only if the content language of the element is known,
  according to the rules of the document language such as those for
  HTML, then language-specific rules must also be applied.  These
  minimally include, but are not limited to, the rules in Unicode's
  SpecialCasing.txt [ref].
