Thank you Bastien, I tried many variations and eventually…
This one worked !
```
function Div (div)
local custom_style = div.attributes['custom-style']
if custom_style then
if (custom_style == 'mots') or (custom_style == 'motspremier') then
  return pandoc.Header(1,div.content[1].content)
else
local pre = pandoc.RawBlock('dokuwiki', '<WRAP ' .. custom_style .. '>')
local post = pandoc.RawBlock('dokuwiki', '</WRAP>')
local content = div.content
table.insert(content, 1, pre)
table.insert(content, post)
return content
end
end
end
```
