On the "new" document?

Regardless, I think that is non-conformant behaviour, but I cannot 
find a reference online to back me up with that statement.

No ... CDATA is syntactic sugar for XML documents ... it isn't 
meaningful at all.  It is just a shortcut for not typing out entities.

Ah ... then you don't have a problem on the way in to the second 
process, only on the way out to your server.

On the way in to your second process you have to have "&amp;" because 
the second process is XSLT ... hence the message from Saxon (I hadn't 
realized you had two processes).

Then I think you are stuck.  What experiments have you run with the 
server?  Have you tried hand-typing &amp; in the URL at the server to 
see how it complains?

Sorry I have no guidance to get around what I believe is 
non-conformant behaviour.
