* The default qualifier type.

*
*
* If a bean does not explicitly declare a qualifier other than {@link javax.inject.Named @Named}, the bean has the
* qualifier @Default.

*
*
* If an injection point declares no qualifier, the injection point has exactly one qualifier, the default qualifier
* @Default.
