For developers: Values of a product attribute
 Each attribute can have a number of values. The variations of a product are created on the basis of these values. For example, if you have an attribute named Size, its values will be similar to S, M, L and XL. If a product can relate to this characteristic, a variation for each of the values can be created.
 For more information about variations, see the For developers: Product variations.
 For more information about attributes, see the For developers: Product attributes section.

  - Id
