Hello all,

We're experiencing difficulties importing xliff 1.2 files we have received (Studio is unable to convert to translable format).

We receive the following error message: 

<SDLErrorDetails time="22/12/2022 18:15:21">

We have checked the xliff file and it is a valid xliff 1.2 file. Also, we can import it into another CAT tool we use (DVX). For this project however, we need to use Studio.

We reviewed the following thread, but it does not seem to be quite the same case: community.rws.com/.../bug-importing-xliff-1-2

Can anyone help provide clues as to why this may not be working? Here is an example the code in question:

<?xml version="1.0" encoding="UTF-8"?>
<xliff version="1.2" xmlns="urn:oasis:names:tc:xliff:document:1.2" xmlns:okp="okapi-framework:xliff-extensions" xmlns:its="http://www.w3.org/2005/11/its" xmlns:itsxlf="http://www.w3.org/ns/its-xliff/" its:version="2.0">

  <body> <trans-unit id="tu7" restype="x-paragraph"> 
    <source xml:lang="fr-FR">ABC DEF GHI.</source> 
    <seg-source>

    </seg-source> 
    <target xml:lang="en-GB"></target> 
   </trans-unit>  
  </body> 
 </file> 
</xliff>

Many thanks for your help!
