Unfortunately, the question cannot be answered in this way because too much additional information is still missing. The shipped XML parser rule for TS files does not contain any language element. This must therefore be a user-specific change. How has the additional XML language element been defined?

Hallo Herr Herrmann,

this is how we add the element. 

Thanks for you help.

The selectable Language Coding does not support an option that includes the underscore _.

As a simple workaround, you could define a new data element that reads the language attribute for translation. This would not be an automatic solution, but at least the correct language Coding could be entered.

Unfortunately, I do not understand what you mean here, can you provide a screenshot of the data element?

This setting will import the language, so that it can be changed.

Hello, do you know if there is a chance that the underscore option will be implemented to passolo in future? Because for our framework Qt the underscore is the preferred format.
