XSL-FO support in Publishing Engine 7.0

Hi Folks--

I know that in previous versions of PE (<=6.x), XSL-FO support was implemented in a multi-stage approach, where the document is transformed into XSL-FO markup, and then a dynamically generated FOSI is used to create the final output. Can anyone verify whether that is still the case in PE 7.0? There was talk a while back of developing XSL-FO support via APP rather than via FOSI, but I haven't heard whether that actually went anywhere.

Thanks!
