Yes, because my <sect3>s are not numbered. So it would look funny to 
read "how we have seen in section 2.3.2.5" as there is no section 
2.3.2.5, only a parent section 2.3.2.

Using only the name of the section is no good idea either, beause 4 
chapters later, the reader cannot remember what and where was "the 
section called 'Running Hello World'". (This is more a problem of the 
print version.)


This is common behaviour of LaTeX's \label and \ref-mechnanism: The 
\label can appear anywhere and the generated text for the \ref takes 
into account the depth of the numbering.

Seems like I have to go into XSLT for that. :-)

What I want seems to be hard, at least for me. So a solution would be 
just not to reference any <sect3>s, onle the parent <sect2>s.
