Peter, Hans,

thanks for looking into this. I had realized something was fishy with  
the ConTeXt converted patterns, so I'd be extremely grateful if we  
could have a corrected version. Hans: do we need the actual  
conversion rules, or would it be enough if Peter or I included the  
actual patterns into lang-agr.hyp? That may be faster and less work  
for you.

Best
