text‹The doc_classcode is a general stub for free-form and type-checked code-fragments such as:

         bash code
         isar code (although this might be an unwanted concurrence 
          to the Isabelle standard cartouche)
         C code.

It is intended that later refinements of this "stub" as done in ‹Isabelle_C› which come with their
own content checking and presentation styles.

text‹Not a terribly deep theorem, but an interesting property of consistency between
ontologies - so, a lemma that shouldn't break if the involved ontologies were changed.
It reads as follows: 
"The structural language of articles should be included in the structural language of
reports, that is to say, reports should just have a richer structure than ordinary papers." ›
