protocol AttributeScope : DecodingConfigurationProviding, EncodingConfigurationProviding, SendableMetatype

A type that organizes attributes into a grouping, and supports dynamic member lookup and serialization of attribute keys. Attribute owners — typically frameworks — define attributes with ``AttributedStringKey`` types. To allow access to attributes with dynamic member lookup, owners create one or more structures that conform to ``AttributeScope``. The scopes provide short names for their attributes that map to the ``AttributedStringKey`` type. The following example shows how to do this: ```swift struct TextStyleAttributes : AttributeScope { let foregroundColor : ForegroundColorAttribute // ForegroundColorAttribute.Value == Color let backgroundColor : BackgroundColorAttribute // BackgroundColorAttribute.Value == Color let underlineStyle : UnderlineStyleAttribute // UnderlineStyleAttribute.Value == UnderlineStyle // etc. } ``` This allows callers to use a syntax like `myAttributedString.foregroundColor = .red`.
