Okay, thanks. I thought that might be the case, but couldn't be sure.

Okay, fair enough. Thanks for the info.

Only whitespace? I can live with that.

Hmm. Does
headline (:title hello :todo-keyword TODO :todo-type todo)
look valid to you as a minimal TODO-type headline? Created via:

  (let ((todo (org-element-create 'headline)))
    (org-element-put-property todo :title todo-title)
    (org-element-put-property todo :todo-keyword "TODO")
    (org-element-put-property todo :todo-type "todo"))
