Support for usernameToken and wsa elements sign

[mabubn]

Hi, first I must say that zeep is amazing library (I didnt found any better solution for python). But I have one problem, I need to sign usernameToken element and also wsa token elements with certificate. Exists som possibilities how to do that with zeep library? In current state only body element and timestamp element are signed, I didnt found any possibility how to sign another xml elements with certificate. Thank you so much
