User Requests & Most Wanted Features
Performance enhancements ?
With the current architecture, FOP uses quite some memory in certain situations, such as larger fo:page-sequences. A number of users have expressed the desire to see this changed.
XSL-FO compliance & features
fo:footnotes in fo:tables and fo:list-blocks are not implemented yet. There is already a patch available
here, that should be reviewed and preferably applied ASAP. fo:floats are currently also unimplemented. Code branch has already been created during Google Summer of Code 2006, so not all is quiet on that front.
support for integer values for keep-together, keep-with-next and keep-with-previous
support for XSL-FO 1.1 features, such as
fo:change-bar-*
Extensions
the table-continuation label extension has so far not been ported to 0.9x, which still keeps certain users from upgrading
