Dear ConTeXt folks,


in ConTeXt I like how I can choose arbitrary names for label and
reference them. I think some time ago it was possible to also use »()«.
This does not work anymore with

        ConTeXt  ver: 2011.11.25 21:29 MKIV  fmt: 2011.11.25  int: english/english

and the following message is in the log file.

        references      > unknown reference [][(N)]


        \definereferenceformat[eqref][left=(,right=)]
        
        \starttext
        \placeformula[(N)]
        \startformula
        	\Pr\{N = n\} = \Pr\left\{ \min_{1 ≤ k ≤ n} S_k > 0 \right\} = p_n^{(1)}
        \stopformula
        
        Is it working? \eqref[(N)]
        
        \CONTEXT\ \contextmark\ \contextversion
        \stoptext


Thanks,

Paul
