Meta-styles for LaTeX 2.10 (or 3.0)


What we should start with, I think, is a description of common classes
of documents in terms of their constituent elements. One of the ways
of doing this is giving document type definitions or dtd's: the SGML
way of looking at documents. I will give one example, using the
following notation:

   ? = optional (0 or 1)
   + = 1 or more
   * = 0 or more
   , = all must occur, in given order
   & = all must occur, in any order
   | = one and only one must occur

I'm thinking of the following document types (classes)

7. proceedings (multi-author book; 1 overall editor, every chapter
   its own author, possibly each chapter its own toc)

   book       = (front, body, back?)
   body       = (chapter|section)+
   chapter    = (chapter_title, chapter_author, toc?, text*, section+)
   section    = (section_title, text*, subsection+)
   subsection = (subsection_title, text*, subsubsection+)
   text       = ...

   front      = (titlepage & details* & toc? & lof? & lot? & prelim*)
   prelim     = (preface|foreword|acknowl|other)
   titlepage  = (title & (author|editor)* & abstract? & date?)
   title      = (title_line+, subtitle)

   back       = ((appendix|glossary|biblio|other)* & index?)
   appendix   = (chapter|section)+

6. book (single-author book)

5. report
   (a definition like the one above should clearly differentiate
    between reports and books, something I've never understood.
    Maybe Leslie could comment on this?)

4. journal
   (consists of 1 or more articles, each with the same components
    as article; journal has title page, author index, table of contents)

3. article
   (existing style lacks
    - address-author differentiation
    - a construction for author list followed by address list
      with references from the first to the latter)

2. memo

1. letter


In other words: I propose (as end of part II)

  - to define document classes in terms of dtd's
  - to translate elements of the dtd into LaTeX commands
    (most of them already exist)
  - implement one or more styles for each class; for instance ARTICLE
    and ARTIKEL1 are instances of the article class (meta-style)
