I like that.  Either as part of the editorial process, or as a
pre-processing step in the Makefile.

AH is the tool from Antenna House?  Looking over their site, I don't see
a free version.  FOP is entirely free, so the is the only possible
choice for Fedora.  Unless I missed something about XEP or AH.

FOP needs to compile with a free Java compiler and run in a free Java
environment to be part of a completely free toolchain.  Personally, I'd
prefer it to be compiled with gcj.

One reason for using gcj for compiling is that if we need to report bugs
with other free software, our components are going to be suspect if they
have been tainted by non-free components during compiling or runtime. 
There are developers who will push bug reports back at us in those
situations, and I support them in doing so. 

As hard as it may be to start, having a completely free toolchain will
be blessing.
