"""
Avoid compiler warnings like "‘struct HNBAP_CriticalityDiagnostics_IE_List__Member’
declared inside parameter list will not be visible outside of this definition
or declaration", which break compiling the sources with -Werror and can't be
ignored with diagnostics as they don't have their own type (unlike e.g.
-Wuninitialized).
This problem is explained further in:
https://github.com/vlm/asn1c/issues/430
To avoid this, convert "SQUENCE … OF SEQUENCE" like here:
CriticalityDiagnostics-IE-List ::= SEQUENCE (SIZE (1..maxNrOfErrors)) OF
SEQUENCE {
…
to "SEQUENCE … OF …-Value" and below that "…-Value ::= SEQUENCE":
CriticalityDiagnostics-IE-List ::= SEQUENCE (SIZE (1..maxNrOfErrors)) OF CriticalityDiagnostics-IE-List-Value
CriticalityDiagnostics-IE-List-Value ::=
SEQUENCE {
…
