Localization support for RadTextBox/password strength?

I have a RadTextBox field used as a password entry field.  Furthermore, I'm using the built-in password strength indicator for this field as follows:

    PasswordStrengthSettings  ShowIndicator="true"

I need for the strength text to be culturally sensitive but I'm not seeing a Localization attribute to work with.  How can this text be set?

Thanks in advance.
