This refers to the study and use of extensible markup and programming languages—most notably XML (Extensible Markup Language)—which allow users to define their own tags, schemas, and data structures for representing structured information. It is a foundational topic for software developers and data architects working with data interchange formats, configuration files, and document standards like XHTML, SVG, and SOAP-based web services.
