[XeTeX] hyphenating words with hyphen

[John Was]

Hello Vadim

In case it's relevant, in English-language typography it is considered very 
bad to hyphenate an expression which is already hyphenated.  TeX will (I 
think) always prohibit this by default, and where it is absolutely 
unavoidable the user needs to put an explicit hyphen \- in the file.  But 
rewriting where possible to avoid the situation would be a better solution. 
This is why typesetters dislike expressions such as 'the 
do-it-later-if-at-all attitude to work' or 'an ethnic-community-oriented 
strategy' (the second, with longer words, is more awkward than the first as 
there is a greater chance that you would need to divide one of the 
components).

Best


John
