DAVENPORT: "Using a Split Document" with Emacs/PSGML

["M.-A. DARCHE" <ma.darche@stellarx.com>]

Hello,

I'm a beginner when it comes to emacs. I've always used vim before.
I have started to use emacs/psgml to write sgml documents.

I need help on "Using a Split Document".
"Using a Split Document" is a very important topic to easily browse 
through big sgml sources.
The problem is that I am not skilled enough to get the 
sgml-parent-document feature of PSGML work, as described at:
http://www.lysator.liu.se/~lenst/about_psgml/psgml.html#SEC9

So concretely, I have a separate *.sgml file for each chapter 
of a book.
How should I specify psgml which DTD to use, when editing one
of those separate files ?

Here is the main file: memoire.sgml
------------------------------------------------------------
<!DOCTYPE BOOK PUBLIC "-//Davenport//DTD DocBook V3.0//EN" [

<!ENTITY Introduction SYSTEM "introduction.sgml">

]>

<book>
&Introduction;
</book>
------------------------------------------------------------

Here is a file for a chapter: introduction.sgml
------------------------------------------------------------
<chapter>
<title>Introduction</title>
<para></para>
</chapter>
------------------------------------------------------------

And here is my .emacs file:
------------------------------------------------------------
; -*- Emacs-Lisp -*-

(custom-set-variables
 '(case-replace nil)
 '(case-fold-search nil)
 '(font-lock-use-default-fonts nil t)
 '(font-lock-use-default-colors t t)
 '(sgml-set-face (quote highlight) t)
 '(sgml-doctype (quote memoire\.sgml) t)
 '(sgml-parent-document (quote memoire\.sgml book chapter chapter) t)
 '(auto-save-default nil)
 '(make-backup-files nil))
------------------------------------------------------------

I would be grateful if anyone could help me with this.

Best regards,

--
