Leo mentioned the risk that by using normal item attributes for sections 
can yield to suprising results if -ppx rewriter start moving declaration 
around or inserting new ones.

I think it makes sense to keep floating attributes in general.  They are 
useful also to turn warnings on/off, for instance.  And it is fine to 
use them for ocamldoc section as well (and also to specify an initial 
header, before the first item).   Now if there is really a need to split 
sections in the middle of a group of mutally recursive declarations, 
using attributes on each declaration is probably fine.

Do you agree?
