[fw-mvc] The Calendar of Dojo DateTextBox Translation

Dojo has rich i18n capabilities. I use Dojo DateTextBox element in my
instance of Zend_Dojo_Form. I wonder how to setup translation for this
element. I mean if I use French translation for instance how to force
the drop-down calendar to display the month name and weeks in French?

I haven't found anything related in the documentation and would
appreciate any help.
