This value is the maximum number of corresponding name values that can be used per Item Specific when creating, revising, or relisting an item on the specified site.

Once you know the site threshold, it can also be helpful to know specific Item Specifics in a category that can have more than one value, such as 'Features'. Multiple values can only be specified for an Item Specific if the corresponding itemToAspectCardinality field of the getItemAspectsForCategory method shows a value of MULTI.
