Another consequence is that you can't (by default) access DTD Notations
in Xpath 2 / Xquery as (unlike, say the ID type) the differences
between the DTD typing and schema typing are irreconcilable when
building the Xpath model.

      The following properties of the unparsed entity information item
      have no value: [notation name], [notation].
