Which two features should a Consultant keep in mind when proposing the use of JSON-based...

The Consultant can use the item section for any type of item list, not only for line items.

Only Contract, Opportunity, Order, and Quote objects are supported when mapping fields in JSON-based mapping.

JSON-mapping allows for filtering individual line items or repeatable content items to display in a document, but Object-based mapping does not.

The data to extract and merge into the template must exist in standard objects.

Documents cannot display attribute data unless the Custom section in the document template is used.
