SOX (Simple Outline XML) is XML with an easier to edit syntax. This is useful for reading and creating XML content in a text editor. SOX was created because developers can spend a great deal of time with raw XML. For many of us, the popular XML editors have not reached a point where their tree views, tables, and forms can completely substitute for the underlying markup language. This is not surprising when one considers that developers still use a text view, albeit enhanced, for editing other languages such as Java.
