In 5.2 we have:
"A variable that is part of another variable (as an array element or a structure element) cannot
appear in a detach clause."
and
"An array section can appear only in clauses for which it is explicitly
allowed."
and
C/C++
"A variable of <generic_name> OpenMP type is a variable of type omp_<generic_name>_t."
and
Fortran
"A variable of <generic_name> OpenMP type is a scalar integer variable of kind
omp_<generic_name>_kind."
and
"event-handle	variable of event_handle type	default"

As there is no explicit allowing of array sections, array sections aren't
allowed in detach, and it must be scalar integer.
The question is if a non-coindexed coarray is a scalar integer variable or
not.
