+A string indetifier of the service, it can be in two forms: class name or service name,
+for the class name it should be prefixed with C<@>, for example: C<@Foo::Bar>.

+The activation container maintains two maps, one for classes and the other for names.
+The first one is useful when we searching for an implementation the second one when
+we need a particular service.
