[NTG-context] How to realize rubytext in Context?

Hi, for an multilanguage document I need to write some rubytext. But I have no idea how to realize this in context. Math-mode is not a solution as the line-breaks with longer rubytext - but maybe it is the only way. Hints are very welcome. Here is a good and short explanation what rubytext is: http://www.w3.org/International/questions/qa-ruby Ciao, P.
