Tax not invalid for defect of form.

No assessment and no charge of the demand of any tax made under this Regulation shall be impeached or affected by reason of any mistake in the name, residence, place of business or occupation of any person liable to pay the tax, or in the description of any property or thing liable to the tax, or by reason by clerical error or other defect of form; and it shall be enough in any such tax on a property or any assessment of value for the purpose of any such tax if the property taxed or assessed is so described as to be generally known, and it shall not be necessary to name the owner or occupier thereof.
