Providers co-existing

Question

This is from the JMS specification:
A provider must be prepared to accept, from a client, a message whose
implementation is not one of its own. A message with a �foreign�
implementation may not be handled as efficiently as a provider�s own
implementation; however, it must be handled.
Is that true for most vendors? has anyone had any experience with that? I mean - it's probably easy enough to somehow receive a javax.jms.Message created by someone else, as this is purely an interface, but I find it hard to believe that internal handling by the other JMS provider works.
Any ideas?

Hi Arnaud -
My problem is actually - where do i need to catch that a client gave me a Message that is not my message.
I mean - It's probably safe to assume that a client may not send a foreign message on one of my topics, right?
so - basically, the only place where I could be getting a message like this is when a client is trying to use my MessageProducer's send() method, and the Message it gives me - is a foreign one.
In this case, you say, I should be able to see if it's instanceof my Message implementation and if not do a conversion?
I don't see any more to that... is there?
