The XML document should have a root element named offers that contains a list of offers elements. Each offers element represents a single offer and must include essential details such as the price, status, and a link to the vendor's store, along with other pertinent information. While the specific contents of an offers element may vary depending on the type of offer (for example, ammunition, weapons, parts, reloading supplies, etc.), every offer must include all required fields to be considered valid for listing.
