/**
 * 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.
