[Orgmode] (org-entry-properties nil 'all) doesn't return inherited properties

[Holger Macht]

Hi,

(org-entry-properties nil 'all) does not return properties specified in
the file (inherited properties) via a directive such as

#+PROPERTY: stylesheet /stylesheets/stylesheet.org

Is this by intention? If so, is there a easy method to return a list of
all properties, also inherited ones?

Thanks,
 Holger
