Thanks Wolfgang. I gave it a try on https://context-on-web.eu/, but it
failed:
Dimensions can be in units of em, ex, in, pt, pc, cm, mm, dd, cc,
bp, dk, or54sp; but yours is a new one! I'll assume that you meant
to say pt, for printer's55points. two letters.
I'm not sure what it is referring to.
TeX complains about the value ".5fw" for the radius key. Hans added last
year the function to add new units to ConTeXt and I used it to set the
radius to half of the width of the framed box.
Use the following version of the setup for the frame which works with
older ConTeXt installations because it doesn't use the feature.
