Needed to configure smart banners in Yandex.
In theory, the yml catalog from Yandex.Market should work as a feed. And the directive itself successfully accepts it when it is loaded.
And in fact - then the formation of ads on the preview cretives from feed gets a wild mishmash of headers, incorrect prices and not understand where pulled descriptions. While the same xml file on YandexMarket displays everything correctly.
I would be grateful if someone would throw a feed structure template for smart banners direct, which really works.
