@jjrondeau, when you define translations, you shouldn't include any separating delimiters (like " : " in this case). So you'd want to replace <term name="scale">Échelle : </term> by <term name="scale">Échelle</term>.

It also looks like you currently don't use this term yet. Instead of

<text variable="scale" prefix=". Échelle : "/>

it would be better to use:

<group prefix=". " delimiter=" : ">
  <text term="scale"/>
  <text variable="scale"/>
</group>

(the group here prevents the "scale" term from being printed when the "scale" variable is empty)

Yes, you're right. I will correct this.

@jjrondeau, @adam3smith already removed these lines from your submission, but we don't allow HTML tags like this for superscript.

The best solution we currently have is to use superscript characters. See the French CSL locale for an example: https://github.com/citation-style-language/locales/blob/b8c370c8a978790d2aeefa302f05f3bfb1478e75/locales-fr-FR.xml#L74

Thank you for the example. I will use it.

this isn't your addition, but these two labels can't possibly be right?

Yes, I will delete one

ditto here

Yes, I will delete one.

this seems way to complex. Wouldn't

<names variable="editor"/>
<names variable="translator"/>
<text macro="title"/>

or something like that work?

we prefer the et al settings in the bibliography/citation line unless you really need to differentiate et al within citations or the bibliography.

Understood.

ditto

Understood.

why not just continue these with else-if. Also, does the style really need that many different URL forms? Can't we simplify this?

Correction made.

what is this for? Seems quite odd.

now you're using both note and annote? You're really not doing users a favor by making them use a style that requires data entry that breaks everything else.

I will delete "annote" and make minimal use of "note".

don't duplicate the subsequent et al here.

OK

subsequent et al makes no sense for bibliography; remove.

Understood.
