You can use it to automate texts in your drawing - something like generalized dimension texts. You can e.g. display/insert a text contating the current drawing name, current user name (e.g. for your title block), current elevation of a blocks (an automatic elevation label), etc. These text are automatically updated when you change the source property (e.g. when you rename your DWG file, login as a different user, etc.).
