    57  * <p>

    58  * This class mainly performs the following two tasks:

    59  * <ol>

    60  *  <li>Takes a {@link Message] that represents a request,

    61  *      and extracts the arguments (and updates {@link Holder}s.)

    62  *  <li>Accepts return value and {@link Holder} arguments for a Java method,

    63  *      and creates {@link JAXBMessage} that represents a response message.

    64  * </ol>

    65  *

    66  * <h2>Creating {@link JAXBMessage}</h2>

    67  * <p>

    68  * At the construction time, we prepare {@link EndpointArgumentsBuilder} that knows how to create endpoint {@link Method}

    69  * invocation arguments.

    70  * we also prepare {@link EndpointResponseMessageBuilder} and {@link MessageFiller}s

    71  * that know how to move arguments into a {@link Message}.

    72  * Some arguments go to the payload, some go to headers, still others go to attachments.
