The schema snippet you posted does not compile with the schema compilers I
have installed, with the following error message:
Complex Type Definition Representation Error for type 'EnumValue'. When
<simpleContent> is used, the base type must be a complexType whose content
type is simple, or, only if restriction is specified, a complex type with
mixed content and emptiable particle, or, only if extension is specified, a
simple type. 'string' satisfies none of these conditions.
