[NTG-context] issue with \definebreakpoint

Dear list, for a document I’m writing, I have the following sample: \setuppapersize[A6] \definebreakpoint [compound] [–]% en-dash \setbreakpoints[compound] \starttext I hyphenate pseudo–classes and pseudo–elements in a justified paragraph. \startalign[middle] But not when centered: pseudo–classes and pseudo–elements. \stopalign \stoptext I need to be able to hyphenate after the en-dash when the paragraph is justified. The problem is that I need to deactivate this breaking point when the aligment isn’t justified (or at least when it is centered). Is there a way to achieve it? Many thanks for your help, Pablo -- http://www.ousia.tk
