}XML supports elements, attributes, entities, comments, CDATA and repeated children. DTD/entity declarations, mixed content, namespace semantics and lossless type round-tripping are unsupported and explicitly rejected. JSON-to-XML uses a root key plus @attributes and #text.
Frequently asked questions
Does it support all XML?

How are arrays represented?

Is data uploaded?
