(i)  waive the requirement under paragraph (d), or

(ii)  invite the applicant to furnish, within a time limit which shall be reasonable under the circumstances and shall be fixed in the invitation, the original of the document transmitted,

provided that, where the document transmitted contains defects, or shows that the original contains defects, in respect of which the national Office or intergovernmental organization may issue an invitation to correct, that Office or organization may issue such an invitation in addition to, or instead of, proceeding under item (i) or (ii).

(f)  Where the furnishing of the original of a document is not required under paragraph (d) but the national Office or intergovernmental organization considers it necessary to receive the original of the said document, it may issue an invitation as provided for under paragraph (e)(ii).
