def _get_language(self, **kwargs):
return kwargs.get(<EOL>'<STR_LIT>',<EOL>self.metadata.get('<STR_LIT>', '<STR_LIT>')<EOL>)<EOL>
Determine what language to render labels in.

        Will first check if there's a language keyword specified in **kwargs.
        If not, will check the default language of the provider. If there's no
        default language, will fall back to 'en'.
