That's really because environment.Request is an interface that what I 
propose is possible : determination of the locale can be interposed in 
the wrapper before actually calling HttpServletRequest.getLocale(). This 
has nothing to do with tweaking the browser's header or 
HttpServletRequest which BTW is not possible

I goes in the direction of what I want to avoid : multiple sources to 
get the locale ;)

However, pluggable mechanism is possible with my second proposal : 
adding Request.setLocale(). This method can be called by whatever 
mechanism you want.

Ah, sorry, didn't notice that. But wouldn't it be better to default to 
"cocoon-locale" ?

The Sun format should be used. What sources are you talking about ?
