|The language_script spreadsheet should list all of the language / script combinations that are in common modern use. The countries are not important, since their function has been overtaken by the country_language_population spreadsheet.|
- If the language and script are both modern, and the script is a major way to write the language in some country, then we should see that line marked as primary.
- Otherwise it should be marked secondary.
Every language that is in official use in any country according to country_language_population should have at least one primary script in the language_script spreadsheet.
If a language has multiple primary scripts, then it should not appear without the script tag in the country_language_population.txt. For example, we should not see "az", but rather "az_Cyrl", "az_Latn", and so on. For each country where the language is used, we should see figures on the script-specific values. The values may overlap, that is, we may see az_Cyrl at 60% and az_Latn at 55%. However, the combination with the predominantly used script must have a larger figure than the others.
This is also reflected in CLDR main: languages with multiple scripts will have that reflected in their structure (eg sr-Cyrl-RS), with aliases for the language-region combinations.
