◆ NODFLT

const std::string goptions::NODFLT = "NODFLT"

When a GVariable : in a structured option schema uses value goptions::NODFLT : :

that key becomes mandatory (must be provided by the user),
and the option becomes cumulative (expects a sequence of maps rather than a single map).

This allows a schema definition to encode both required fields and repeated entries.

Practical consequence:

The user can specify multiple entries for the same option (sequence of maps).
Each entry must contain all mandatory keys; optional keys are back-filled from schema defaults.
