[MSJ, MDL]How to designate a password text item ?

Hi All,

I noticed there is a TEXT_PASSWORD attribute for text item in V8 MDL, which can make a text item as a password input item, very cool !

But I have to have such a text item in MSJ. How to do this ?  (I know I need to design a text item hook function, but this function is not easy to code)

Any help are appreciated.
