                            an old fashioned flat text file (which contains the data) which also references another flat text file (called a schema) which contains the structure of that data
                                                            
                                                     
                        
                                                
                        
                        
                            a plain text file, so you could easily create and edit the file using Notepad
                                                            
                                                     
                        
                                                
                        
                        
                            a simple text file--just like HTML, but unlike a WordPerfect or DBase file, for example
                                                            
                                                     
                        
                                                
                        
                        
                            a simple text file, which can be transferred across the Internet just like HTML
                                                            
                                                     
                        
                                                
                        
                        
                            a text file you can edit with any editor like WordPad
                                                            
                                                     
                        
                                                
                        
                        
                            a well structured, plain text file
