Hello Mr. Kay,
When you say "the best serialization format for XML
documents is... XML" , what do you mean? I understand,
that serialization means - encoding of objects into a
stream of bytes which can be transmitted over the
wire. Serialization is essentialy used for lightweight
persistence and for communication via sockets or RMI.

When we will transmit String or Java DOM object, they
will be serialized automatically..

Regards,
Mukul
