Please consider committing attached patch. Commented-out call-template
does nothing so we can just customize our customized templates further
to support 1.76.
I've just performed the build with Ubuntu 13.04/docbook 1.76.1 - it works.
(In case the call-template generated something it would appear in
bookindex.html only.)

That work is done already and it's results are countable and observable
differences. (See comments in the xslt.)
For example, with DSSSL we don't get a chapter TOC when the chapter
contains only one sect1 (with XSLT we get the TOC with the one item).
We also had subtoc for sect1/refentry and sect1/simplesect, but with
XSLT it's absent.
So if all such differences are not important, let's move forward.
