JAXP 1.2 doesn't define what happens to xsl:message. I believe Xalan sends
it to the warning() method of the ErrorListener (I'm not sure in what
format). Saxon allows you to specify a MessageEmitter using a non-JAXP
interface.

I think that JAXP 1.3 endorses the Xalan mechanism.

Remember that the order in which messages are written is
implementation-defined.
