(a) All bonds issued by the authority under this chapter shall be issued and validated under and in accordance with Article 3 of Chapter 82 of this title, the "Revenue Bond Law," except as provided in this chapter, provided that notes and other obligations of the authority may, but shall not be required to, be so validated.

(b) Bonds issued by an authority may be in such form, either coupon or fully registered, or both coupon and fully registered, and may be subject to such exchangeability and transferability provisions, as the bond resolution authorizing the issuance of such bonds or any indenture or trust agreement may provide.

(c) Bonds shall bear a certificate of validation. The signature of the clerk of the superior court of the county in which the issuing authority is located may be made on the certificate of validation of such bonds by facsimile or by manual execution, stating the date on which such bonds were validated; and such entry shall be original evidence of the fact of judgment and shall be received as original evidence in any court in this state.

(d) In lieu of specifying the rate or rates of interest which bonds to be issued by an authority are to bear, the notice to the district attorney or the Attorney General, the notice to the public of the time, place, and date of the validation hearing, and the petition and complaint for validation may state that the bonds when issued will bear interest at a rate not exceeding a maximum per annum rate of interest (which may be fixed or may fluctuate or otherwise change from time to time) specified in such notices and petition and complaint or may state that, in the event the bonds are to bear different rates of interest for different maturity dates, none of such rates will exceed the maximum rate (which may be fixed or may fluctuate or otherwise change from time to time) so specified; provided, however, that nothing in this Code section shall be construed as prohibiting or restricting the right of the authority to sell such bonds at a discount, even if in doing so the effective interest cost resulting therefrom would exceed the maximum per annum interest rate specified in such notices and in the petition and complaint.

(e) The terms "cost of the project" and "cost of any project" shall have the meaning prescribed in this chapter whenever those terms are referred to in bond resolutions of an authority, in bonds, notes, or other obligations of an authority, or in notices or proceedings to validate such bonds, notes, or other obligations of an authority.
