If your translator did not add the translation for each message to your XLIFF file (see An XLIFF File) before sending the file back to you, you must manually add each translation to your XLIFF file.
Add each translation, enclosed in target tags, immediately following each source element, as shown in the following example:
<source>original English message</source> <target>[translation in desired language]</target>
Insert the target language attribute (after the source language attribute) in the XLIFF file, as shown in the following example:
<file tool="mdbXliff" source-language="en" target-language="fr" original="myProg.xlf" . . .>
You can use a commercial editor to change the language ID code or you can use either XMsgUtil or XMsgTool with the update only flag.
