They shall not be deemed or taken to be any part of or title of such chapters, articles, divisions, sections or subsections; nor, unless expressly so provided, shall they be so deemed upon amendment or re-enactment; nor shall they be construed to alter the otherwise intended meaning of any provision of this Code.
