A set of extensions which correspond to preferences.
The module provides structures that represent known values for each keyword
in Locale [`extensions`](crate::extensions) with semantic meaning.
# Syntactic vs Semantic Extension Handling
This module ensures that only valid, recognized values are used, providing semantic validation.
It would reject invalid values such as `-u-hc-BB` because `BB` is not a known hour cycle. This
is ideal for applications that require strict adherence to standardized values and need to
prevent invalid or unrecognized data.
If you need to construct syntactically valid Locale extensions without semantic validation,
allowing any valid key-value pair regardless of recognition, consider using the
[`crate::extensions`] module.
