Implementation

The Factura Afecta implements the FacturaAfectaInterface, which extends the base DocumentInterface. This ensures type safety and allows for document-specific behavior. 
namespace libredte\lib\Core\Package\Billing\Component\Document\Contract\Document;

interface FacturaAfectaInterface extends DocumentInterface
{
    // Document-specific methods and properties
}
