Thanks! Our current model hasnt been anywhere near the XSModel. Ive taken
over a old project and its been an uphill struggle to get to grips with all
the various interfaces. Ive had a quick peep at the XSModel and it looks as
if it will open up many of our current restrictions. It does seem to be
exactly what is required although now I have a lot of code to rewrite and
figure out.
