Thanks. Works a treat. One more question, where can I get these
hyphenation files for asian languages (such as japanese).
I'm far from sure hyphenation is even a valid concept
in Japanese.
Well, digging around:
http://marc.info/?l=fop-dev&m=102992807207069&w=2
While this is mostly about line breaking, hyphenation may happen
under
certain, apparently very rare circumstances. Some more info is in the
wikipedia: http://en.wikipedia.org/wiki/Kinsoku_shori
I wonder whether the rules there are reflected in the Unicode line
breaking properties, which would mean that FOP 0.95ff would handle
this properly.

Only partially, if I'm correct. As a fall-back, the UAX#14
implementation in FOP allows breaks between /any/ pair of CJK
ideographs.
(see: http://markmail.org/search/?q=CJK+linebreaking#query:CJK%
20linebreaking+page:1+mid:uykln4qu3gz6r45d+state:results)
As mentioned in the post, this is simplistic, and may very well lead
to a layout that is undesirable/suboptimal from the POV of someone
who is versed well enough in either one of the related languages.
(see the Korean example attached to the OP in that thread)
Someone once started more detailed work on this, and an initial patch
is available in Bugzilla #36977, but this hasn't been incorporated in
the codebase yet, since there were concerns about the approach
operating 'on top of' UAX#14 (unnecessarily increasing iterations
over the same character sequences).
Also, how does one convert a Tex file into a valid hyphenation XML
file?
I don't think there's a tool available to do so directly, although,
from the last time I researched this topic, I do seem to remember
that there are tools that convert TeX hyphenation files into a
generic XML format. Subsequently, with a minimum of effort, such an
XML file could then be transformed via XSLT to match the format used
by FOP.
HTH!
