Rails 3 - is it possible not to display the attribute name in the error message ?

when displayed using

- target.errors.full_messages.each do |msg
  %li= msg

I get obviously displayed :

3 errors
Email can't be blank
Password can't be blank
Agreement status : You must acknowledge that you agree to our Terms of
Use and Privacy Policy and hat you are over 14 years old.

but I would like to display Only the error message on the 3rd
attribute ... getting
3 errors
Email can't be blank
Password can't be blank
You must acknowledge that you agree to our Terms of Use and Privacy
Policy

is it possible ? I don't want to use base, as I need later to check
on error for this attribute....

thanks for you suggestions
