There are two documents you may find useful for working with SOX.

The SOX document you will find most helpful in your work is:

• SOX Tutorial: PDF, 198k (This document covers the basic and advanced features of the SOX language, including namespaces, inheritance, and polymorphism.)
  

• The SOX v2.0 specification is available via Commerce One's SOX download area and the current SOX World-Wide Web Consortium submission is available at http://www.w3.org/TR/NOTE-SOX/. Both sites will also report on the ongoing XML schema efforts, and Commerce One will provide examples by updating the schematized version of xCBL.
