Daniel, I do not want to start a flame war here but I think
you are being
contradictory here. The OP said that he is not sure whether
he needs XML
Schema validation or not. Instead of just ignoring this
topic altogether,
in your reply you started spreading FUD about XSD and
promoting Relax-NG
(about which OP haven't said a word). Now when I present
arguments against
your XSD FUD, you are calling it promotion and off-topic.
Not very nice,
IMO.
