I would like to get something like:

1.1 Theorem instead of Theorem 1.1.

Seems simple enough but can't figure out how to switch the number and the text. I have the following MWE:

\defineenumeration[theorem][

  prefix=chapter,

  text=Theorem,

  style=italic, 

  headstyle=bold,

  headcommand=\groupedcommand{}{.},

]

\starttext

\chapter{}

\section{}

\starttheorem

This is a theorem

\stoptheorem

\stoptext

Many thanks,

Jethro
