[O] attachments in parent

[Andreas Leha]

Hi all,

As it seems, attachments are not found when they are attached to
a parental header.  Is that on purpose?

IMO, it would be nice if attachments would be searched for up the
hierarchy as well.  The attachment directory is not inherited, as
it seems.

Here is an example illustrating my question (you'll have to
attach something yourself to make it work, though):

--8<---------------cut here---------------start------------->8---
* Example
** Test Attachments                                                  :ATTACH:
:PROPERTIES:
:Attachments: sample_attachment.pdf
:ID:       B1024BF6-48F1-4300-9D0D-831A410BB40B
:END:

[[att:sample_attachment.pdf][This]] is found.

*** In Subsections

[[att:sample_attachment.pdf][This]] is not found.
--8<---------------cut here---------------end--------------->8---

Regards,
Andreas

PS: the relevant part of my setup:
--8<---------------cut here---------------start------------->8---
(require 'org-attach)
(setq org-link-abbrev-alist '(("att" . org-attach-expand-link)))
--8<---------------cut here---------------end--------------->8---
