"12.5.2.12 Argument presence and restrictions on arguments not present

A dummy argument or an entity that is host associated with a dummy argument is
not present if the dummy argument
[...]
* does not have the ALLOCATABLE or POINTER attribute, and corresponds to an
  actual argument that
  - has the ALLOCATABLE attribute and is not allocated, or
  - has the POINTER attribute and is disassociated."

That probably means:

a) NULL(mold) as actual argument is allowed
b) For scalars, it should just work
c) For arguments with descriptors, one needs to add:
   (actual.data == NULL) ? NULL : actual
