:relfileprefix: ../../
:mrdocs:

Component‐private type to enable extraction of values held by format contexts during the postprocessing stage of determining the format specification (typically performed by the `FormatSpecificationParser`). This type exists so that `FormatSpecificationParser` can update FormatterSpecificationNumericValue to the value contained by a Standard `basic_format_arg` using the Standard `visit_format_arg` function.
