 Attribute      | Compulsory | Type | Definition
 ---------------|------------|------|--------
-class          | *no*       | string | The targeted class. If no class is passed, the type applies to the current class. The current class is assumed to be an entity. If the "class" attribute is passed, [the class annotated with `@Type` is a service](external-type-declaration.mdx).
+class          | *no*       | string | The targeted class/enum for the actual type. If no "class" attribute is passed, the type applies to the current class/enum. The current class/enum is assumed to be an entity (not service). If the "class" attribute *is passed*, [the class/enum annotated with `@Type` becomes a service](external-type-declaration.mdx).
 name           | *no*       | string | The name of the GraphQL type generated. If not passed, the name of the class is used. If the class ends with "Type", the "Type" suffix is removed
 default        | *no*       | bool   | Defaults to *true*. Whether the targeted PHP class should be mapped by default to this type.
 external       | *no*       | bool   | Whether this is an [external type declaration](external-type-declaration.mdx) or not. You usually do not need to use this attribute since this value defaults to true if a "class" attribute is set. This is only useful if you are declaring a type with no PHP class mapping using the "name" attribute.
