How does one define a "chapter" in HTML? A Section? Unless one can
work in the abstractions of the *author* one is missing the boat
entirely...

Bollocks. Most people avoid the grottier features of SGML and everyone
recognises that this is the correct thing to do. I don't think anyone
frowns on DYnaText, or the other SGML systems available, and *none* of
these support the full language. In fact, if you want an easily
parseable SGML subset that retains 98% of the usefule features of
SGML, I suggest reading the TEI spec (which you obviously have not
done yet).

The tree structure you describe is not your invention. Every man and
his dog in document processing has seen this. This is *inherent* in
any information system. DSSSL starts with this because it recognises
explicitly the tree, and also recognises the value of tree
transformations in document processing. I should note that DSSSL-Lite
is now being developed with the specific aim of being used for WWW and
that the tree transofmration stuff was left off because it was thought
"too difficult".

Ha ha ha. SGML *is* coming. Be afraid :-)
