// PatchMergeInstruction An operation that recursively updates items of the selection, or adding the value if the selection is empty.
// If the value is not an object, it is used directly, otherwise each key-value member is used
// to create or update a member of the same name in the target and the same process is applied recursively for each object-typed value
// (similar to RFC 7396 (https://tools.ietf.org/html/rfc7396#section-2) JSON Merge Patch, except that null values are copied
// rather than transformed into deletions).
// NOT_FOUND exceptions are handled by creating the implied containing structure.
// To avoid referential errors if an item's descendant is also in the selection, items of the selection are processed in order of decreasing depth.
