How to add custom translation to module in 1.7.x?

[Rosad0]

Hello,

I can not figure out how to add translation to any module in PS 1.7. I have example on Wirepayment module, I tried also on another, custom modules. None of listed below ideas did not work.
I understand these translations are not showing in .xlf translation files automaticaly. So:

1. How to force prestashop to add my custom translation and make it visible via backoffice?

2. Which code is correct for (if there is difference)?
a.) standard module,
b.) theme module.

      {l s='Your order on %s is complete. abc' sprintf=[$shop_name] d='Wirepayment.Shop'}<br/>
      {l s='Please send us a bank wire with:' d='Modules.Wirepayment.Shop'}
      {l s='Teste' d='Modules.Wirepayment.Shop'}
      {l s='Teste 2' d='Wirepayment.Shop'}
      {l s='Teste 3' mod='ps_wirepayment'}
      {l s='Teste' d='Module.Wirepayment.Shop'}
