Thank you very much Wolfgang!

Now I can get exactly what I need, see the example below (also tested
with my larger document, available at
http://www.maths.lth.se/matematiklth/personal/mickep/analysB2ht16/analys-context.pdf).

I'm very happy about this solution. Also, thanks to Hans for giving us
this very nice tool (I usually only write to the list when I have
problems, sorry)!

With the new beta you can set a default prefix for enumeration references,
i.e. you can write \startquestion[knuth] in your document without the need
to add a question or answer prefix.

\setupinteraction[state=start]

\define[1]\QuestionTextCommand
{\doifreferencefoundelse{answer:\currentconstructionreference}
     {\goto{#1}[answer:\currentconstructionreference]}
    {#1}}

\define[1]\AnswerTextCommand
{\doifreferencefoundelse{question:\currentconstructionreference}
     {\goto{#1}[question:\currentconstructionreference]}
    {#1}}

\defineenumeration
[question]
[text=Question,
   headcommand=\QuestionTextCommand,
   referenceprefix=question]

\defineenumeration
[answer]
[text=Answer,
   headcommand=\AnswerTextCommand,
   referenceprefix=answer]

\starttext

\startquestion[knuth]
\input knuth
\stopquestion

\page

\startanswer[knuth]
\input knuth
\stopanswer

\stoptext
