The trouble is that different classes can have different names for
sections and their hierarchies. So we really need some standard way of
defining the relative structure elements within a class and also between
classes when changing document classes.
We've discussed this lots of times now but not really found a final
solution. A LyX DTD was the last best suggestion that incorporated
standard levels/structure elements (like s1, s2 etc. for each section
depth) and all classes could be approximately mapped to (be they LaTeX or
SGML/XML).
I'm inclined to think that DocBook might be a suitable superset for
mapping all document classes to. It seems to cover a huge range of
possible document structure elements (only a small proportion of which are
used in any given LaTeX document class).
Then the layout files would need a little extra info per paragraph style
to say what logical element that paragraph style maps to. Changing
between document classes is then a matter of comparing logical elements
rather than environment names.
