The document can be found here:
http://www.xith.org/tutes/GettingStarted/html/

Let's say in section 8 you add a new subsection "foo" at the beginning
of the section. Then a link which used to point to "The Model" now
points to "foo". This is what I want to avoid.

I assume (and this has proven to be true) that most users actually copy
at the beginning of each page and paste it into forums. So, I'm not
document.

Actually I can do this, but most users won't see this link, because they
copy&paste the link from the TOC and the listing of sub(sub)sections at
the beginning of each section. (I assume there is no magic involved and
the links in the TOC stay the same like before if I use the technique
above.)

I already tried to explain it above. Links within the document are not a
problem.

I hope the problem is now clearer.
