Should be there as well.

In Fortran 2008, it is in "5.2 Type declaration statements", p.88, lines 1-4
(same/similar to F2018).

In Fortran 2003, it is in "5.1.2.5  DIMENSION attribute", p. 78, ll. 3-5:

"The DIMENSION attribute specifies that an entity is an array.  The rank or
rank and shape is specified by the array-spec, if there is one, in the
entity-decl, or by the array-spec in the DIMENSION attr-spec otherwise."

That choice makese sense, e.g. for:

complex(kind=my_cmplx_kind), intent(in), asynchronous, dimension(n,n) :: A, B,
C, D, v(n)

such that one does not need to repeat all the lengthy stuff just to denote the
different array spec for 'v'. (On the other hand, whether there is a need to
specify everything in several different ways and permit overriding in addition
is another question.)

Thus, the standard made a sensible choice – and the standard is the standard
:-)

Done so: CLOSE as INVALID.

Better some noise than missing some real bugs or useful improvements. Hence:
Thanks!
