What is XML?
XML or Extensible Markup Language is a specification developed by the W3C
(World Wide Web Consortium).
It is a derivative version of Standard Generalised Markup Language (SGML) and was designed especially for web documents. XML allows users to create their own tags, enabling the definition, transmission, validation, and interpretation of data between organisations and their supporting applications.
In the context of B2B electronic commerce, XML and its supporting technologies, combined with other associated Internet protocols allows organisations to use the traditional ideas of Electronic Data Interchange (EDI) and bring them to the Internet.
XML is supported by a number of technologies that make it more than just a language or core syntax. (For example, the ability to query, transform and integrate between applications are all possible with XML).
GS1 XML 
provides a standardised and predictable structure for electronic business messages, enabling business partners to communicate business data rapidly, efficiently and accurately, irrespective of their internal hardware or software types.
