Thank you, that's absolutely correct, as I confirmed by putting a
`message' form at the end of that function. I have now changed
nxml-mode.el as in the diff below. With that, I get the required
indentation, 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 change to `nxml-compute-indent-from-matching-start-tag' introduces a
local variable `only-end-tag' to distinguish between the line starting
with "analytic", and the last two lines.
Now, the next thing I see is that if, after this indentation, I do
`fill-paragraph', it goes back to the old indentation. Anyway, I'll
deal with that later. For now, I'll make do with these changes, which
at least give me the indentation I want.
Thanks very much for your help.
Best regards,
Raghu.
