Hi Stanislas,

seems this is still pending:

> Description: Make TS_CASE object and ts_parser support key value 0. When

Your patch changes the TS parser:

-       if ($objStrName)        {
+       if (isset($objStrName)) {

I'm not sure but have the feeling that $objStrName contains the full object
path, therefore it is never empty. Please check if this is really needed.

Part 2 of the patch (tslib_content.php) is ok. +1
