> attempted this, using:
> {code:java}
> public @interface DomainService {
>     // ...
>     @AliasFor(annotation = Named.class, attribute = "value")
>     String logicalTypeName() default "";
> } {code}
> however it results in:
> {code:java}
> Caused by: org.springframework.core.annotation.AnnotationConfigurationException: @AliasFor declaration on attribute 'logicalTypeName' in annotation [org.apache.isis.applib.annotation.DomainService] declares an alias for attribute 'value' in annotation [javax.inject.Named] which is not meta-present.

> which I think means that @Named is not itself annotated to be a meta-annotation; presumably required by Spring's annotation processor.
