User is trying to open for translation an XLIFF 2.0 file with Trados Studio and is getting the error message
The ' ' character, hexadecimal value 0x20, cannot be included in a name.

The issue is caused by an “id” attribute value inside the file, in the form of an whitespace that is used inside the attribute value, causing Trados Studio not to parse the file. 
The solution would be to replace the whitespace with an underscore. This should fix the issue and Trados Studio should be able to open the file for translation. 
This change should not affect the localization process.
