Mappings now supports using the JSON array-of-objects structure as both source and target documents when building a mapping.

JSON documents converted from tabular data formats, like CSV, XML, etc., do not have a top-level object by default. Until now, it was impossible to set the list context correctly, without manually adding a top-level object.

With the expanded support of the JSON specification in Mappings, JSON array-of-objects structure can be used as the source and target documents, without the need for manual adjustments and additional transformations before and after the mapping request.
