You mean where there's a (Unicode) en-dash or em-dash? (Either in the  
original input text, or as a result of a font mapping.)

If so, you may want to set the parameter

   \XeTeXdashbreakstate = 1

in your preamble. This will cause XeTeX to allow a break after the  
Unicode en- and em- dash characters, in the same way as TeX does by  
default after an explicit hyphen.

I'm not sure if either of the parts of the compound word will be  
eligible for hyphenation in this situation; normally, if there's an  
explicit hyphen/dash, TeX does not attempt to further hyphenate the  
two parts. If you want to allow that, you probably need some  
additional code to introduce some (possibly zero-width) glue.
