[NTG-context] languagespecifics

Hello, Is there something like \startlanguagespecifics[fr] ... \stoplanguagespecifics in mkiv? Does it make sense, to keep the module t-french.tex? I would like to integrate \setcharacterspacing[frenchpunctuation] everywhere (text, headers, footers and so on), but when a user loads the module and changes settings for headers or footers afterwards, that setting would be overwritten. Thus, if there are no methods, to do such things, I would drop the module and french specific settings have to be set up on a per document basis. What do you think? -- Peter
