Craig, I've just come back from the lots.ch conference today and I had some time in the train to write that protocol handler I was talking about (for the data: protocol). Find the sources here:
http://cvs.apache.org/~jeremias/datahandler.zip To make it work you have to put them somewhere in your project (or in FOP and recompile) and specify the following system property for the virtual machine: -Djava.protocol.handler.pkgs=org.apache.fop.util.protocols Adjust accordingly if you change the package names. The implementations defers to Batik's implementation of RFC2397 as I hinted would be possible.
