Despite all the valuable recommendations in this thread I implemented
something simple for my very specific use case of a music database
where I want self-explaining links with the already existing and
complete heading structure and don't want to add any ID, CUSTOM_ID or
<<target>>. See this example:

#+begin_src org
,#+STARTUP: oddeven showeverything

Specs for outline path of links to a heading, any combinations allowed
including none:
- "/" delimits headings of adjacent levels.
- A leading "/" requires matching the top level heading.
- "//" delimits heading levels with 0 to n discarded heading levels
between them.

Demo examples:
- Goes to tag 1: [[*Chopin/Prelude]]
- Goes to tag 2: [[*/Prelude]]
- Goes to tag 3: [[*d/c//b/a]]
- Goes to tag 4: [[*d/c/b/a]]
,* Foo
,** Bach
,*** Prelude
,** Chopin
,*** Prelude :1:
,* Prelude :2:
,* d
,** c
,*** Bar
,**** Baz
,***** b
,****** a :3:
,*** b
,**** a :4:
#+end_src

Limitations of this simplified implementation:
- Export of links with a path to a heading is not supported.
- Links to a heading with "/" that existed before are broken.
- There may be other issues for your use case already discussed in the
current thread (
http://lists.gnu.org/archive/html/emacs-orgmode/2018-03/msg00231.html
).

Due to the limitations this implementation is for private use only and
not meant to be commited upstream although the format of the attached
patches might imply that.
