There is \definestartstop; for usage see the exampe i made for wybo. 

\setuplayout[width=100mm]

\let\normalbegin\begin     

\let\complexbegin\normalbegin          

\def\simplebegin#1%
  {\getvalue{start#1}\bgroup
   \def\end##1{\egroup\getvalue{stop##1}}}

\definecomplexorsimple \begin           

\definedescription
  [description]
  [location=hanging, 
   margin=standard,
   headstyle=bold]

\definestartstop
  [descriptions]
  [before=\blank\startpacked,
   after=\stoppacked\blank,
   commands=\let\item\description]  

\starttext 

\dorecurse{10}{This one is for Wybo. }

\startdescriptions

\description {aap:} is a monkey, but much more can be told
about this animal;s for example they are hairy, mostly
brown or black and they resemble people a lot. 

\item {noot:} is a vegetable; again there are many kinds
and you will get very fat if you eat lots of them. 

\startdescription {this is a rather long item:} 

it is not very interesting in itself, but gives me the
opportunity to tell you something about the description
environment: it is like an itemize, but with user-supplied
labels which are printed bold. 

\stopdescription

Not yet, but it's on my to do list, since I sometimes need it too.
