XML is the 'lingua franca' for e-documents. It provides a standard mark-up language for defining the structure of documents, thereby enabling their transmission, validation and interpretation between applications and between organisations.

The ambition is that rather than convert XML documents into HTML, future browsers will be XML-based, displaying XML documents natively and avoiding any conversion process as XHTML documents will look like regular XML to these browsers.
The web services link
Web services has been one of the big technology rallying points for the last two years. Promising a standard way for distributed applications to exchange information and interrogate each other, web services is a combination of XML and standard web traffic protocols. It uses XML-based data to describe what services and information an application provides and then transfers that information using standard web traffic to other applications on a network or on the Internet. Since the means to describe those services and the messages the services can send are both well defined XML formats, web services provides a universally understandable, machine and human-readable way for applications to integrate with each other and pass information between themselves.
