Exactly.

Ok.  I think that it is indeed necessary, now that we are moving HTML
more towards a book like formatting, for which USE_NODES set to 0 would
make sense.  It is actually how texi2html output was designed, but, even
though there are plenty of ways to customize the navigation panel
buttons that come from texi2html, there is no existing way to do it
more dynamically.  In the texi2html style, buttons are hardcoded to 
use section directions (and section names).

The downside is that it increases the code to maintain, may need
additional specific test cases...
