The World Wide Web has grown to become the world's digital library, making available information from a vast sea of resources. This phenomenon is due in large part to the success of the Hypertext Markup Language (HTML), and it's universal methods for displaying data. In order to enable the next level of web applications, we need flexible methods for defining, interacting with, and exchanging data for a variety of domain-specific applications.
The Extensible Markup Language (XML) and the related XML-based recommendations provides a core infrastructure that will enable this next level of web applications. The success of this technology will be dependent upon the industry's ability to produce applications that are interoperable. Within these pages, you will find test suites that can be used to determine whether or not a particular implementation conforms to the W3C recommendation. NIST staff work with appropriate W3C representatives to ensure that our tests complement W3C recommendations. Any ambiguities and/or interpretations that result from those tests are subject to confirmation by the appropriate W3C working group responsible for the recommendation.
