> But how can it be done with so many exceptions to the rules? If the rules are sufficiently good then you don't need so many exceptions. English (especially with UK as opposed to American hyphenation rules) is probably the worst of the European languages and even here the exception dictionaries used by TeX are fairly manageable 10s or 100s of words not thousands. Other European languages that have more regular hyphenation rules can get by with fewer exceptional words. > There are lots > of words that should not be hyphenated; names on persons, streets and > places, days, months and so forth. If you need to turn off hyphenation based on semantic context then clearly you'll need markup in the FO file. But you can turn off hyphenation (hyphenate="false") on the surrounding element (or on an fo:inline that just carries this attribute for a single word.) > Acctually, there's even a need for not > splitting two words sometimes That's what   is for isn't it? > Sorry, I'm just a TeX (or acctually LaTeX) newbie, so I'm not familiar with > the concept of patterns. TeX doesn't (normally) use a dictionary of words to provide hyphenation but rather uses a particular pattern matching algorithm based on patterns of hyphenation for each language. You can then have a dictionary of hyphenated words (again per language) for cases when the general rules don't work. Whether or not your document gets correctly hyphenated will depend on the hyphenation method used by th eFO formatter, so if you need to customise it, it makes sense to customise this for each formatter rather than in the XSL FO file. (If you are using xmltex (passivetex) to format xxx.fo then you can stick the command \hyphenation{this-word-hyphenates-here} in a file xxx.cfg (I was going to use Supercalifragilisticexpialidocious as an example, but according to a search I did in google, TeX hyphenates that one correctly without need for an exception... > Unless you're working with very narrow columns, there is seldom a need for > hyphenating words with less than, say, 6 characters, You'd probably have to tolerate excesive white space stretching with such a rule.
