Castor Exception : The prefix 'xml' is reserved

[Christophe Geraud]

I got the following exception with Castor: "The prefix 'xml' is reserved
(XML 1.0 Specification) and cannot be declared."
I got this exception using or not a mapping file.
Can anyone tell what it means ?

Here is the stack trace :

java.lang.IllegalArgumentException: The prefix 'xml' is reserved (XML 1.0
Specification) and cannot be declared.

If I simplify it works, so somethings unsupported i think
