I am applying it incorrectly, or it does not work with the buffers created by \grabbufferdata:

    \setupwhitespace[none]
    \setupindenting[none]
    \starttexdefinition unexpanded startBufTest
      \bgroup
      \dosingleempty\dostartBufTest
    \stoptexdefinition
    \starttexdefinition dostartBufTest [#SETUPS]
      \getrawparameters[BufTest][xx=yy,#SETUPS]
      \grabbufferdata[TestBuffer][startBufTest][stopBufTest]
    \stoptexdefinition
    \starttexdefinition stopBufTest
      \startnarrower[left,right]
      \startparagraph
        \BeforePar{\dontleavehmode\llap{? }}\GotoPar
        \inlinebuffer[TestBuffer]
      \stopparagraph
      \stopnarrower
      \egroup
    \stoptexdefinition


\starttexdefinition stopBufTest
  \startnarrower[left,right]
  \startparagraph
    \dontleavehmode\llap{? }%
    \blank[overlay]
    \inlinebuffer[TestBuffer]
  \stopparagraph
  \stopnarrower
  \egroup
\stoptexdefinition
