By default, interface-based services of a mORMot server will always
return a JSON array (or a JSON object, if
TServiceFactoryServer.ResultAsJSONObject is
true).
With some kind of clients (e.g. if they are made by a third party), it could be
useful to return XML content instead.
Your mORMot server is able to let its interface-based services return XML context instead, or in addition to the default JSON format.
