that is not what the instructions say, I go by the instructions. it says to use bing and optionaly to use esri. it does not state esri has to be used in the instructions. it says to use bing imagery, and IF esri is used to allign it with bing, twice is stated to use bing imagery, not only for allignment but imagery. and that esri optionaly may be used. you now require esri while that is not instructed and invalidate the work. wasting time. mappers look at the instructions. if validators make comments that are different from the instructions then either the instructions are wrong or the validator. so either of those need to be fixed so we don't waste work.
