Optional ReadonlyuniqueRestricts every tag to a single string.
When true, a tag carries a single string, so that a member stating several values spreads them across languages
rather than stacking them under one. Fixes the arity the content is resolved at: a bare string under every tag
where the constraint is stated, an array of strings under every tag otherwise.
Inheritance — a child may add the constraint but not drop it: overriding a unique-tagged parent with a non-unique-tagged child is rejected.
Optional ReadonlyminMinimum string length in characters.
Inheritance — child may only raise the minimum length.
Optional ReadonlymaxMaximum string length in characters.
Inheritance — child may only lower the maximum length.
Optional ReadonlylanguageAllowed language ranges.
When specified, every tag the map is keyed by must match one of the given TagRange values under RFC 4647
basic filtering. Each range is a basic language range (a sequence of subtags or the standalone * wildcard);
extended ranges such as en-* are not accepted. Empty arrays are ignored. Language tags, which identify a
language rather than select one, are described by tag instead.
Inheritance — child may only drop accepted ranges.
Constraints accepted by the dictionary shape factory.
Bounds the content a tag may carry and the languages the map may key it by. Length bounds are matched against each string separately, so a value is held to them whatever language it is stated in.
