DOCBOOK-APPS: map the id with the anchor for sections

There is any way to automatically generate a correspondence between ids
of sections and generated anchors of those sections, when I generate the
html files with the backend html?


Example:

	<book>
		<chapter><title> C1 </title>
			<section id="s1"><title> S1 </title>
				...
			</section>
			<section id="s2"><title> S2 </title>
				...
			</section>
		</chapter>
		...
	</book>
	
I parse the SGML files. After that, I obtain:
	book1.html
	c123.html
	s2.html

The map file (comma separated values) witch I want to obtain for the
'id' and 'link' is:
	s1, c123.html#s1
s2, s2.html

Note: I use 'sgmltools -b html' to parse the sources.
