For other values, a _Bad Option_ error is emitted
and the `u:id` option is ignored.

### `u:locale`

Replaces the _locale_ defined in the _function context_ for this _expression_.

A comma-delimited list consisting of
well-formed [BCP 47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt)
language tags,
or an implementation-defined list of such tags.

If this _option_ is set on _markup_, a _Bad Option_ error is emitted
and the value of the `u:locale` _option_ is ignored.

During processing, the `u:locale` _option_
MUST be removed from the resolved mapping of _options_
before calling the _function handler_.

Values matching the following ABNF are always accepted:
```abnf
u-locale-option = unicode_bcp47_locale_id *(o "," o unicode_bcp47_locale_id)
```
using `unicode_bcp47_locale_id` as defined for
[Unicode Locale Identifier](https://unicode.org/reports/tr35/tr35.html#unicode_bcp47_locale_id).

Implementations MAY support additional language tags,
such as private-use or grandfathered tags,
or tags using `_` instead of `-` as a separator.
When the value of `u:locale` is set by a _variable_,
implementations MAY support non-string values otherwise representing locales.

Implementations MAY emit a _Bad Option_ error
and MAY ignore the value of the `u:locale` _option_ as a whole
or any of the entries in the list of language tags.
This might be because the locale specified is not supported
or because the language tag is not well-formed,
not valid, or some other reason.

### `u:dir`
