Excuse me. Since when is it a prequisite that chapter headings
be put into the TOC!! 

I do admit that Books have a TOC. The TOC is just there to help
navigate a Book even printed! The epub requires that there is a TOC
like structure for navigating the ebooks. They do not have to correspond
to the chapters of a book!! 

There are many books with out TOCs. Especially, older books. It is only
a newer convention. A Chapter, is defined semantically differently. It marks
a logical division in a book. A TOC on the other hand has a logical relation
to the chapters of a book. NOT the other way around. Of course, it is nice to 
have the functionality that during processing to know that here is a chapter 
and please make a TOC entry! Yet, to infer the start of a chapter one does not
need a explicit chapter marker.  

I have not tried it, but I should be possible to make an ebook that does not
have any chapter navigation nodes except one to the beginning of the file containing
content. At least there is not anything forbidding it! It is a convention. The epub has
no way of identifying a chapter unless you tell it that a chapter is suppose at point X.

Keith.

It's what goes into the Table of Contents in an ebook. And ebooks for the most part don't let you pass "Go" without distinct chapters in hand. So you won't get far with only undifferentiated chapter headings.

 
       The real question is true semantic markup needed! You yourself have mention that the semantics is
       in the mind.
       Besides, what is a Chapter title? It, too is a paragraph, in most cases!
