204 | A scalar defined by scalar_ref will inherit all attributes of the referenced |

205 | one, except its id attribute. |

206 | If there is no id specified, an implicit one is assigned to this new scalar. |

207 | The scalar with implicit id can only be used inside the scope where it |

208 | is defined, it can not be referenced, nor be processed. |

209 | It is useless to define an scalar without id inside scalar_definition. |
