Schema description for arbitrary data formats with the Data Format Description Language

A cornerstone of the Service Oriented Architecture is the ability to exchange documents or messages in a clearly defined way. The usual approach to this in new systems is to create documents in XML, allowing the use of XSD (XML Schema Definition) for document description and exchange. However, when interacting with legacy applications, or for some other specific cases, XML is not always a possibility or the best option. This leaves the need for a standard way to define schema for non XML data. DFDL is a proposed solution to this problem, based around the use of standard annotations to XML schema to allow any physical representation for a data model.
