The positive test branch looks for an allowance whose category code is G and does not also require the tax scheme to be VAT. The negative branch does require that scheme. Both branches write cbc:ID)='G' with no space before the equals sign. The seller identifier the test accepts is a company identifier on a VAT tax scheme, or the tax representative's company identifier on a VAT tax scheme.",
