This will be the visible name of the Solution Folder in the Visual Studio Solution Explorer. You can use a parameter/variable to make the value dynamic, for example $MyCustomFolderName$ - this will enable you to dynamically set the value in a wizard extension or one you have defined in a CustomParameter element. You can also use a well known automatically populated parameter such as $projectname$.
