SOX was created because developers can spend a great deal of time with raw XML. For many of us, the popular XML(3)have not reached a point where their tree views, tables and forms can completely substitute for the underlying(4)language. This is not surprising when one considers that developers still use a text view, albeit enhanced, for editing other languages such as Java. SOX uses(5)to represent the structure ofan XML document, which eliminates the need for closing tags and a number of quoting devices. The result is surprisingly clear.
