[Orgmode] skip entry with inherited tags

[Matthias Teege]

Moin,

I'm using a simple skip-function to exclude todos from a list.

(defun my-skip-someday-and-scheduled ()
  ""
     (org-agenda-skip-entry-if 'scheduled 'regexp ":SOMEDAY:"))

That works when the tag was assigned to an entry but not when it was
inherited from a parent. How do I get all tags for an entry?

Many thanks
Matthias
