It is sufficient once one reads B.2.8.

  B.2.8   CHARACTER* form of CHARACTER declaration

  In addition to the CHARACTER*char-length form introduced in Fortran
  77, Fortran 90 provided the CHARACTER([ LEN = ] type-param-value)
  form.  The older form (CHARACTER*char-length) is redundant.

This clear applies to the BNF give by R403 -> R404 -> R421.
