Locking of content in XML

Hello,

I have a XML file and I would like to lock the content of one element. If I mark the element as "Not translatable" it will not be imported and hence cannot be seen in the editor. But I would like to have it imported so that the translator can see the content of the element but cannot change it. How would that be possible?

As an alternative it would be nice to lock the whole segment that contains the element automatically (the element is always put as a separate segment not as Inline Tag). Is there a way to do that?

Thanks in advance.

Regards,
Christiane
