if the required global-trade-data does not exist,
simply submit identifier_exists FALSE and then
do not submit any global-trade-data for that item --
do not submit any brand, gtin, or mpn for that item.
note that the merchant (shop) brand is set in the account,
submitted for all items automatically, and cannot normally
be submitted as the brand value for any item.
also, be certain that the product truly does not have the (google) required
global-trade-data as assigned by the brand-manufacturer -- for example,
most apparel items only require a valid brand; certain brand items must
have global-trade-data or cannot be submitted; identifier_exists FALSE
cannot be used if the required global-trade-data simply cannot be easily
submitted or cannot be easily located, such as for older or used items.
