Which give the following LaTeX code:

The third and fourth cases are very elegant as they use only
aliases (which
are dropped from the LaTeX code).
Third and forth are non-existent syntax in Org, these lines are
just treated
as comments and are removed during export.
OK. But the information in these 2 comments is correctly used to
replace the
alias (heading-c and heading-d) with the label generated by org
during the
export. See the last 2 references in my example: these references
are correct.
They thus have been correctly processed from heading-c and heading-d
to sec-3
and sec-4... these comments are thus not simply removed... right?
This is only by chance, because a simple text search does match these
two lines.
if you'd happen to have the string headline-a anywhere in the file,
the link would point to the enclosing section.
In the case of the :CUSTOM_ID: property, the property is also used
to convert
the alias to the label (heading-a to sec-1) but additionally an
extra label
(heading-a) is created and not used.
That's why, when creating references to sections I found the #
+CUSTOM_ID very
elegant... But apparently I don't have to use such syntax...
Not if you want to have reliable links, no.

I wanted to know the recommended way of doing references...
Thanks a lot for your help.
