cXML (commerce eXtensible Markup Language) is a protocol, created by Ariba in 1999, intended for communication of business documents between procurement applications, e-commerce hubs and suppliers. cXML is based on XML and provides formal XML schemas for standard business transactions, allowing programs to modify and validate documents without prior knowledge of their form. Each cXML document is constructed based on XML Document Type Definitions (DTDs). Acting as templates, DTDs define the content model of a cXML document, for example, the valid order and nesting of elements, and the data types of attributes.
