The following snippet sounds a bit confusing to me, though admittedly
I am not a Fortran hacker:

+       <li>Null pointers (including <code>NULL()</code>) and not
+       allocated variables can be used as actual argument to optional
+       non-pointer, non-allocatable dummy arguments, denoting an absent
+       argument.</li>

Is "actual argument" a standard term?  "as actual argument to ...
arguments, denoting an absent argument" sounds a bit tricky.

(Something may not be right with singular and plural here, too:
first is singular, the second one plural, the third one singular
again.)

+       <li>Non-pointer variables with <code>TARGET</code> attribute can

"with the <code>TARGET</code> attribute"?
