All such revenue bonds shall contain on the face thereof a statement to the effect that the authority shall not be obligated to pay the same or the interest thereon except from the revenues of the project or the portion thereof for which they are issued and that neither the faith and credit nor the taxing power of the local agency or of the state or of any political subdivision thereof is pledged to the payment of the principal of or the interest on such bonds. The issuance of revenue bonds under the provisions of this part shall not directly, indirectly, or contingently obligate the local agency or the state or any political subdivision thereof to levy or to pledge any form of taxation whatever therefor or to make any appropriation for their payment.
