In function org-edit-src-code there is already support for derived modes from org-mode:
,----
|   (let ((mark (and (org-region-active-p) (mark)))
| 	(case-fold-search t)
| 	(info (org-edit-src-find-region-and-lang))
| 	(full-info (org-babel-get-src-block-info))
| 	(org-mode-p (or (org-mode-p) (derived-mode-p 'org-mode)))
`----

(defun org-mode-or-derived-mode-p ()
  "Check if the current buffer is in Org-mode or a derived mode."
  (if (derived-mode-p 'org-mode) t nil))

Using org-mode-or-derived-mode-p would change the function like this:
,----
| In function org-edit-src-code
|   (let ((mark (and (org-region-active-p) (mark)))
| 	(case-fold-search t)
| 	(info (org-edit-src-find-region-and-lang))
| 	(full-info (org-babel-get-src-block-info))
| 	(org-mode-p (org-mode-or-derived-mode-p))
`----

org-mode-p could be replaced step by step with org-mode-or-derived-mode-p to enhance the support for org-mode derived modes.

I need org-mode-or-derived-mode-p instead of org-mode-p in org-entry-properties.

It would be great if org-mode-or-derived-mode-p could be added!

Thanks,
  Stefan.
