Section numbering starting from zero, not one

Section numbering starting from zero, not one

[Alex Leray via ntg-context]

Hello,

I'd like to have roman numerals prefixed sections, but starting from 
Zero and not One (even if I know that roman numerals don't have a sign 
for 0).

Is there a way to achieve this? My code looks like that at the moment:

###

\setuphead[section][conversion=Romannumerals]

\starttext
\setupheadnumber[section] [-1]
\startsection[title={Section zero}]\stopsection
\startsection[title={Section one}]\stopsection
\stoptext

###

Thank you,

Alex

Answering my own question… this fits my needs:

###

\defineconversion[romannumeralszero][0, I, II, III, IV, V, VI, VII, 
VIII, IX, X, XI, XII, XIII, XIV, XV, XVI, XVII, XIII, XIX, XX, XXI]

\setuphead[section][conversion=romannumeralszero]

\starttext
\startsection[title={Section zero}]foo\stopsection

\startsection[title={Section 1}]bar\stopsection
\stoptext

###

Sorry for the noise

you can often find hints in the test suite (many small files)
