When you use “location=hanging” and set the margin to 0pt contexts sets the margin to 1.5em. I don’t know what do you want to achieve but maybe “location=serried” is what you want.
Another question: does it make sense, that context overwrites the margin=0pt? Imagine, you have some wrapper (simplified user-friendly macro): \definedescription[SpecialDesc][location=hanging, margin=1em] % 1em = default \def\SetMargin#1{\setupdescriptions[SpecialDesc][margin=#1]} Now, because of this (for me unexpected) behaviour, the \SetMargin becomes more complicated: if #1 == 0pt then location=serried else margin=#1 endif IMHO, it would make more sense, if context just accepts the user supplied margin, and when location=hanging and margin=0, then it prints a warning message: "Hey, you can get the same with location=serried!" ;) -- Peter
