After the creation of the condominium, no description of a condominium unit shall be deemed vague, uncertain, or otherwise insufficient or infirm if it sets forth the identifying number of that unit, the name of the condominium, the name of the county or city in which the condominium is situated, and either the deed book and page number where the first page of the declaration is recorded or the document number assigned to the declaration by the clerk. Any such description shall be deemed to include the undivided interest in the common elements appertaining to such unit even if such interest is not defined or referred to in the description.
