Textual descriptions of the specific product.
Free form text, mandatory. Can also be thought of as the ordering description. Should be a simple, single sentence that describes the product like "6 channel power amplifier". Try and be as generic as possible, don't load up the short description with hyperbole like "worlds finest or critics agree or top of the line", save that for the long description and features.
Free form text. Ideally should be a sentence or two but can be a paragraph extolling the virtues of the product in a more descriptive manner.
Free form text. Can be a paragraph or two explaining the benefits of this product in non-technical language that the reseller could use in their proposals to end users.
