Does anybody know if there are some example xsl-fo files out there on the net which show how to use the tags that the AFP output engine adds to Apache FOP?
This page http://afp-renderer.sourceforge.net/afp-extensions.html does a good enough job of listing what the extra extension tags are, but I have no idea where they fit in the existing schema of xsl-fo tags.
The page you mentioned is quite old. Better look inside the Apache FOP project where this has been integrated. Check the AFP extension section of http://xmlgraphics.apache.org/fop/trunk/output.html
The examples in there are almost complete but here is a small XSL:FO input:
