Is it not possible to encode exceptions in the hyphenation dictionary? DSSSL has an 'hyphenation-exceptions' property which takes a list of strings. I'm unsure if it has been implemented, though. http://dsssl.netfolder.com/paragraph-flow-object.htm > In addition to this, hyphenation can be indicated locally.

Prince6 does't try to go beyond Tex. -h&kon H?kon Wium Lie CTO ??e?? howcome at opera.com http://people.opera.com/howcome
