descriptionProvides negative considerations regarding something, most typically in pro/con lists for reviews (alongside [positiveNotes](https://schema.org/positiveNotes)). For symmetry
In the case of a [Review](https://schema.org/Review), the property describes the [itemReviewed](https://schema.org/itemReviewed) from the perspective of the review; in the case of a [Product](https://schema.org/Product), the product itself is being described. Since product descriptions tend to emphasise positive claims, it may be relatively unusual to find [negativeNotes](https://schema.org/negativeNotes) used in this way. Nevertheless for the sake of symmetry, [negativeNotes](https://schema.org/negativeNotes) can be used on [Product](https://schema.org/Product).
The property values can be expressed either as unstructured text (repeated as necessary), or if ordered, as a list (in which case the most negative is at the beginning of the list).
