DOCBOOK-APPS: Double Side and FOP with 1.53

Hi,

I have tried with Saxon, Xalan using a custom style sheet using with
parameters on the command line but with Fop 20.4 along with XSL
stylesheets 1.53.0 I can not get a double sided print outpout.

Is this something with the Stylesheets or with Fop ?
