This document discusses XML and its uses. It provides examples of how XML is used to transfer data between systems, such as between electricity meters and meter reading software. It also discusses tools for working with XML, such as XML Spy, as well as user interface frameworks that use XML, such as WPF and Silverlight. The document emphasizes that understanding purposes and concepts is more important than technical terminology, and that the importance of XML depends on one's career and role on a project.
