Hi Ihor

The headings could be in different files, yes.

AFAIK, citations don't link two exact points. Footnotes do.

I don't understand the option of "include", but I think it wouldn't be the case.

I really think footnotes would be a particular case of this option.

** Reference in file A
:PROPERTIES:
:ID:       978-84-362-7195-9
:END:

...
A “comment line” starts with a hash character (#)
[n:102@978-84-362-7195-9] and either a whitespace character or the
immediate end of the line.
...


** Notes in file B

[n:102@978-84-362-7195-9] The hash character is important in orgmode.

Thanks for reading

Could exist a more general case than footnotes?

A kind of footnotes that work between different files?


Maybe the syntax could be [n:LABEL@ID]

Where the ID would be the unique ID of the heading.

Example:


** Reference
:PROPERTIES:
:ID:       978-84-362-7195-9
:END:

A “comment line” starts with a hash character (#) 
[n:102@978-84-362-7195-9] and either a whitespace character or the 
immediate end of the line.
...


** Notes

[n:102@978-84-362-7195-9] The hash character is important in orgmode.

I am not sure if I understand. Is the above in different files?

Random suggestions:

1. Use citations
2. Use a normal footnote and #+include statement in its definition to
   incorporate a text from a different file during export.
