How to cross-references sections in a thesis? When using cross-references in a thesis for cross-referencing to specific sections, do we have to use section numbers or section names would be fine too? 

example:


  As discussed in the Discussion section, ...


vs


  As discussed in section 3.4, ...


If possible, please answer with a citable reference.

I remember reading that both are correct, but know I cannot find it! I think it was in the book "How to write a better thesis?" by Evans, Gruba and Zobel.

Thanks!
Intuitively, it's a matter of taste.  Both are indeed correct.


  As discussed in the Discussion section/Section 3.4


But the former is less usable, because finding the Discussion section is harder than finding Section 3.4, so I strongly advocate the latter.
