3) Keep heading punctuation as in the source. In particular, keep occurrences of literal « - » (space-hyphen-space) as « - » (the existing French docs use a hyphen here).

### French instructions about technical terms

The spec also states that the `username` and `password` must be sent as form data (so, no JSON here).

### `scope` { #scope }

The spec also says that the client can send another form field "`scope`".

The form field name is `scope` (in singular), but it is actually a long string with "scopes" separated by spaces.

Each "scope" is just a string (without spaces).

        return resourceName.substring(pos + 1);
