DOCBOOK-APPS: Synopses in XSL-FO stylesheets

The support for classsynopsis, methodsynopsis, and related elements 
seems substantially more advanced in the Docbook XSL stylesheets for 
HTML than for FO. In the next release, would it be possible to get the 
FO stylesheets upgraded to at least the same level of support for these 
elements as is currently available in HTML?
