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)
OK, I didn't understand that post, but by the looks of it FOP does not
support Asian languages. Seeing as most Asian languages (I would think)
are monospaced, am I correct in saying that it would be something that
would be best done at the XSLT level (ie, build your own hyphenation
rules into an XSLT and put them in blocks)?
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!
