[PHP-NOTES] note 130573 added to language.attributes.overview

It is possible to use self:: keyword in class-level attribute to reference current class, although it is actually placed "outside" class definition. Private constants also are visible. For example:

#[ApiResource(
    operations: [
        new Get(
            uriTemplate: '/{id}',
            normalizationContext: ['groups' => self::NORMALIZATION_GROUPS],
        ),
    ]
)]
#[ORM\Entity]
class MyEntity
{
    private const array NORMALIZATION_GROUPS = ['groups'];
    ...
}
