XML is becoming the standard way to exchange information between different applications. Increasingly more businesses will do data exchange with their partners on the Web using XML technology.
The success of XML based data exchange depends on ability of both sides of communication channel to process XML messages unambiguously . WSDL and XML Schema specification in general are subject to interpretation by multiple third parties. Certain schema features are not supported, or not supported consistently, by commonly available third party XML processing and development tools. If such features are used in a schema design, the generated XML messages by one vendor's software will not be processed consistently by receiving parties utilizing another vendor's XML processing software. As a result unexpected results or communication failures are possible. The logical solution to this problem is to use only XML Schema features commonly supported by all major XML processing tools. The goal of this project was to develop an extensible software framework for validating a given XML Schema or WSDL document against a set of the XML Schema best practices formulated at AT&T.
