The "elemental" specification is an F95 feature, so one could make a
reasonable case that there is no reason why F90 mode should support this.
"recursive", on the other hand, is an F90 specification.

I use the following in my .emacs to get F95 syntax highlighted:


(defface f95-keyword-face
  '((t (:foreground "plum1")))
  "F95 keywords face.")

(defface f95-function-face
  '((t (:foreground "azure1")))
  "F95 function name face.")


(defvar f95-font-lock-keywords
  (list
   '("\\<\\(pure\\|elemental\\)\\>" . 'f95-keyword-face)

   ;; Override existing highlighting of 'elsewhere', etc, but not in comments.
   '("\\<\\(null\\|cpu_time\\|elsewhere\\)\\>[ \t]*("
	 (1 (if (f90-in-comment) 'font-lock-comment-face 'f95-function-face) t))

   ;; Plain forall should not really be highlighted without trailing '(',
   ;; but is in existing f90-mode.
   '("\\(\\<end\\> *\\)?\\<forall\\>" .
	 (0 (if (f90-in-comment) 'font-lock-comment-face 'f95-function-face) t))

   ;; Highlight the extra 'dim' keyword for these functions.
   '("\\<\\(\\(max\\|min\\)loc\\|ceiling\\|floor\\)\\>[ \t]*("
			 ("\\<dim\\>" nil nil (0 'f95-keyword-face)))
   )
  "Highlights extra F95 keywords.")
