XML
Extensible Markup Language. A simpler and easier-to-use subset of the
Standard Generalized Markup Language (SGML), with unlimited,
self-defining markup symbols (tags). Developed by the World Wide
Web Consortium (W3C), the XML specification provides a flexible way
to create common information formats and share both the format and
the data on the Internet, intranets, and elsewhere. Designers can create
their own customized tags to define, transmit, validate, and interpret
data between applications and between organizations.
