A markup language in which semantic content is conveyed by surrounding test with named tags in pointed brackets, as in <entry>Here is some text</entry>. It is referred to as "extensible" since the set of defined tags can be augmented at will, unlike in such other markup languages as HTML. Abbreviated XML. XML is extremely useful for data sharing since the definitions of the tags can be exported along with the data and XML-encoded documents can easily be parsed and transformed into other encodings. It is used in some voting systems to express ballot definitions and tabulation reports.
