Attributes provide more information about the values you submit to Amazon. You can find them in the Amazon XML Mapping marked with an "at" symbol (@).
A common example is the Unit of Measure (example: SleeveLength@UnitOfMeasure).
If you want to send something that is 30 inches long, you would enter "30" in the field and have an attribute set to "IN".
Below is a list of all the valid inputs Amazon will accept for attributes, capitalization matters. If your value is not on this list, Amazon will return an error.
