A power of attorney which satisfies the requirements of § 18-16-2(b) is not prevented from being a statutory short form power of attorney, as that phrase is used in the sections of this chapter, by the fact that it also contains additional language which:
(1) Eliminates from the power of attorney one or more of the powers enumerated in one or more of the constructional sections of this chapter with respect to a subdivision of the statutory short form power of attorney not eliminated from the form by the principal;
(2) Supplements one or more of the powers enumerated in one or more of the constructional sections in this chapter with respect to a subdivision of the statutory short form power of attorney not eliminated from the form by the principal, by specifically listing additional powers of the agent; or
(3) Makes some additional provision that is not inconsistent with the other provisions of the statutory short form power of attorney.
