I have made some progress, with this function. I tried changing the
definition of `nxml-compute-indent-from-previous-line' as follows:
----------
diff --git a/lisp/nxml/nxml-mode.el b/lisp/nxml/nxml-mode.el
index e2b51bc..f2e185e 100644
--- a/lisp/nxml/nxml-mode.el

- (+ (if (eq before-context 'start-tag) 1 0)
- (if (eq after-context 'end-tag) -1 0))))))))
+ (message "bc=%s ac=%s" before-context after-context)
+ (cond ((and (eq before-context 'mixed)

+ (t (+ (current-column)
+ (* nxml-child-indent

+ (if (eq after-context 'end-tag) -1 0))))))))))
(defun nxml-merge-indent-context-type (context)
"Merge the indent context type CONTEXT with the token in `xmltok-type'.
----------
This almost gives me the indentation that I want, as in,
----------
<article>
<section>
<title>Kant lipsum</title>
<para>Let us suppose that the noumena have nothing to do with
necessity, since knowledge of the Categories is a posteriori.
Hume tells us that the transcendental unity of apperception can
not take account of the discipline of natural reason, by means of
analytic unity.</para>
</section>
</article>
----------
The only thing is that the last line in the para, the one starting with
"analytic", is not indented as I want it. It should be indented to the
same column as the previous line, the one starting with "not".
I have put
(message "bc=%s ac=%s" before-context after-context)
to give me some idea of what is happening. However, it does not produce
any message when I go to the troublesome last line of the para, and
press tab.
I'd appreciate if someone can help with this problem. If it is better
off on emacs-devel, I'll move it there.
Thanks,
Raghu.
