How to add () to equation number?

How to add () to equation number?

[Mr. Wang Lei]

Hi, I want put the equation numbers into a pair of ( )
when refering them. For example, if I have writtten 
a formula numbered 1.1 and labeled [eq:number1], then when 
I use \in[eq:number1], I want get (1.1) other than 
1.1 . I knew put the \in[..] into (\in[...])
works, but I want to know if it can do such job 
automatically.

\definereferenceformat[informula]  [left=(,right=),text=equation]

works. using "find + grep" get the above solution. :-)

An alternative is using left/right labels (actually implemented since
chinese needed it): 

\setuplabeltext
  [figure={{whow (},{)}},
   infigure={{in figure (},{)}}]

\definereferenceformat[infigureA][left=(,right=),text=figure]
\definereferenceformat[infigureB][label=infigure]

\starttext

\placefigure[here][c]{}{}

\infigureA[c] en \infigureB[c]

\stoptext
