DOCBOOK: Chapter and sect1 both creates H2 html tag

[�yvind Heggen]

Hi

My document is structured like this :

Book
  Chapter
        sect1
          sect2
                sect3
                /sect3
          /sect
        /sect1
  /Chapter
/book

When building html and html_chunks, Book crates a H1 tag, Chapter and
sect1 creates H2, sect2 creates H3 etc.

Question:   1 Why does Chapter and sect1 create the same tag (H2) ?
                2 How do I get them to create difftrent html tags so
that I can set            diffrent fonts and text size with CSS
                3 or some other way to set diffrent fonts and color in
XSL(preferably            nr 2) 

Thank you
