Specify here the name of your end-user visible multilingual string program loader.
The string loader exposes those *MTXT variables that are compiled into the Framework during the build. It allows you to use your own multilingual text for Framework captions such as the "Clear List" on the Instance list.
Refer to the shipped source code of RDML function UFU0003 in process UF_SYSBR for details of how and when you should change this property.
This property is in the Framework Details tab.
