/**
 * Set the expected data type of the output message. If the actual message type is different at runtime, camel look for
 * a required {@link Transformer} and apply if exists. If validate attribute is true then camel applies
 * {@link Validator} as well. Type name consists of two parts, 'scheme' and 'name' connected with ':'. For Java type
 * 'name' is a fully qualified class name. For example {@code java:java.lang.String}, {@code json:ABCOrder}. It's also
 * possible to specify only scheme part, so that it works like a wildcard. If only 'xml' is specified, all the XML
 * message matches. It's handy to add only one transformer/validator for all the XML-Java transformation.
