[NTG-context] How not to print the chapter number

[Eric Détrez]

I wish to print my texte as

I Foo

1 Bar one

1.1 barbar one

1.2 barbar two

2 Bar two

2.1 foofoo one

2.2 foofoo two

I don't want the Roman I printed in the numbering.

With contextmark II I just added
\setupsection[section-3][previousnumber=no]
but it doesn't seem to work in mark IV.

Is there a way to do it ?
