[NTG-context] issue with \setuptyping (and XML sources)

Dear list, the issue I’m experiencing comes from XML sources typeset with ConTeXt. I have tried, but I found no way to get a minimal sample. For code fragments in the XML source, I use: \bgroup\xmlprettyprinttext{#1}{none}\egroup To which I apply: \setuptyping [style={\tt\wider}, margin=yes, align={right, broad}, blank={3*halfline}, before={\blank[3*halfline]}, after={\blank[3*halfline]}] Could anyone be so kind to explain me why the first three options from \setuptyping work (style, margin and alignment), and the other three don’t work at all? Sorry, I think it has to be a stupid mistake of mine (but I don’t know which one it might be). Many thanks for your help, Pablo
