Symptoms: 
Tags in a locked sub-segment are wrongly exposed in the SDLXLIFF file created by SDL TMS when a TM match is applied to such segments.
When the file is opened in SDL Trados Studio, tags in locked sub-segments are exposed as a plain text instead of the nice purple representation. As a result, the target files will be corrupted. 

Explanation: 
Modifications were recently made in SDL TMS to handle the order/anchoring of tags. These modifications didn’t apply yet to tags in locked sub-segments.

Resolution: 
With this fix, tags in locked sub-segments will now be handled properly.

SDL-hosted customers should contact SDL Support to arrange for this hotfix to be deployed.

Customers who host SDL TMS themselves should download the installer forSDLTMS11.0 Hotfix for TMS-10540.exe from the following FTP site: ftp://sdlpatches:5dlpatch35@ftp-emea.sdlproducts.com/SDL TMS/11.0/CU3/Hotfix.

Notes: 
This issue does not affect word counts.
The issue does not occur if the task is opened in the SDL TMS Translation Interface.
Jobs affected with this issue will need to be recreated.

This issue was detected in a previous version of SDL TMS. Per SDL Engineering policy, the Engineering team provides hotfixes for the latest release of SDL TMS to encourage our customers to run the latest version of SDL TMS to benefit from the latest features and fixes.
