Summary

0006309: NamedNumber should be mapped to constant in TTCN-3

Description

In chapter "9.1 Transformation rules for ASN.1 types and values" in transformation rule 12) the handling of named numbers is defined.
Currently the named numbers are ignored.
This is valid for mapping the type itself. However the named numbers are given to provide specific meanings to specific values. This can be used in TTCN-3 as well.
The named numbers shall be mapped to constants in TTCN-3.
A proposal for the name of the constant is as follow: the type name as prefix, followed by an underscore and the name of the named number and a final underscore to avoid name clashes.

To keep the named number in the format of constant is also important as a change of the named number in the ASN.1 module would be transparent for the TTCN-3 module, if the TTCN-3 constant is used inside TTCN-3 rather then a direct number(which may have changed the meaning in ASN.1)

Additional Information

e.g.:
Definition in ASN.1:
  Color ::= INTEGER {red(0),green(1), blue(255) }

Mapped constant in TTCN-3:
  type integer Color;

  const Color Color_green_ := 1;

  const Color Color_red_ := 0;

  const Color Color_blue_ := 255;
