So you are saying that the binary, after reading a latex file, isn't quite
aware of the DOM-structure of the file, while after reading a Context-file
it is?

It seems that this information is less needed when building an HTML-file
instead of a PDF. I mean, it needs to do something like chapter-heading ->
H1, but after that it couldn't care less about whether or not that chapter
ends.

I will look at the sources you mentioned.
