Here is a very simple mechanism, I do not take 
care of all the bells and whistles [1] of \in.

\def\myin[#1:#2]{
   \expandafter\ifx\csname in#1\endcsname\relax
     \writestatus{warning}{referenceformat in#1 not defined}
     \in[#1:#2]
   \else
     \csname in#1\endcsname[#1:#2]
   \fi}

\definereferenceformat[insec][text=Section]

\starttext
\section[sec:one]{One}

\placeformula[eq:1]\startformula
   a = b
\stopformula

What happens in \myin[sec:one] equation \myin[eq:1].

\definereferenceformat[ineq][left=(,right=)]

What happens in \myin[sec:one] equation \myin[eq:1].

\stoptext

[1] Remember that \in is a very complex command. You can use
\in section [sec:one] instead of \in{section}[sec:one] and also do 
subnumbering.

I do not know how. You can abuse left, right options to do this, but I 
think that there is a better way.
