hover property
Hover is hover's answer: the type and documentation as the language server itself renders them, so it is prose meant to be shown, not parsed.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? hover;
