How the xml translate works ?

When you see translate="label" module="checkout", this one tells to Magento that it should pass the value in the <label> tag through the checkout module's data helper's translate method before displaying it.

Eg: echo Mage::helper('checkout')->__('your string');

If the module attribute is not present, the core module is used. You may specify multiple tags to be translated with a space delimited string.

As far as I know, this is supported in the System Configuration section, and the layout xml <action> nodes (for translating paramaters) only.

<checkout_cart_index translate="label" module="checkout"> //i added the module here
        ...
</checkout_cart_index>
