I've copied the following example from the ConTeXt archive:
\defineoverlay[frames][\positionoverlay{frames}]
\setupbackgrounds[text][background=frames]
\startMPpositiongraphic{frame}
if unknown context_apos : input mp-apos.mpiv ; fi ;
\MPgetposboxes{\MPvar{self}}{\MPanchorid}
if nofposboxes = 1 :
draw posboxes[1] ;
fi ;
\stopMPpositiongraphic
\startpositionoverlay{frames}
\setMPpositiongraphic{one}{frame}
\setMPpositiongraphic{two}{frame}
\stoppositionoverlay
\starttext
This \hpos{one}{word} should be \hpos{two}{framed}.
\stoptext
Frames are misplaced, so I don't know if that's a bug or something else
has been updated/changed/deprecated. Thank you in advance.
As a step-up to further integrated (more lmtx-ish) support for this the
next upload will have this:
\defineoverlay[frames][\positionoverlay{frames}]
\setupbackgrounds[text][background=frames]
\startMPpositiongraphic{frame}
getposboxes("self","anchor") ;
if nofposboxes = 1 :
draw posboxes[1] ;
fi ;
\stopMPpositiongraphic
\startpositionoverlay{frames}
\setMPpositiongraphic{one}{frame}
\setMPpositiongraphic{two}{frame}
\stoppositionoverlay
\starttext
This \hpos{one}{\strut word} should \hpos{two}{\strut also be framed}.
\stoptext
