I didn't follow that. Do you mean that the "EXPORT_" is a special prefix?
Or "EXPORT" is any backend prefix I choose?

Should that be added to these?

=====
:options-alist '((:hugo-front-matter-format "HUGO_FRONT_MATTER_FORMAT" nil
org-hugo-front-matter-format)
(:hugo-tags "HUGO_TAGS" nil nil)
=====

I already tried above, but I don't know how to get the ":HUGO_TAGS" value
from the property drawer, in subtreep export only, in the body filter (with
only body and info available).

If it is a full document export, I can use the "org export parse headlines"
function (forgot the name, on the phone at the moment) to get the
properties from each headline. But the same doesn't work when exporting
just one sub-tree.

Otherwise, you simply need to retrieve it and store it before calling
> `org-export-to-file' or whatever.


Hmm, will give this a try.. may be look at the pre export hook?

Thank you.
