How do I display the first day of the week Monday?

Hello everyone! Faced a problem. I need the [DAY_WEEK] tag to show 1 as Monday in Russia, but 1 as Sunday in the US. In the GWS, you need to select all languages on the tag [e], and then the tag itself will put the correct first day of the week for the desired country, but this does not work in the WFS. Any ideas how to do this in WFS?

Hello, check this thread. The WFS is working different from GWD/GWS in this regard. We already requested this functionality being implemented into WFS too. Meanwhile you would need to use expression with language tags, which is not only really cumbersome, but also impossible, as the list of available language tags is not in documentation.
