Using XML as a serialization format gives you more flexibility
than Java's built-in serialization. The recipient can use
a different class to process the data than the sender.
You can modify the sender and recipient implementations
independently without having to keep the code bases in sync,
as long as the transport schema remains the same.
You don't have to implement both ends in the same programming
The main drawback is that it takes extra work to implement the
XML serialization and deserialization code. Whether the
added flexibility is worth the extra effort depends on
the application; in many cases it is.
