# XML Specifications

These World Wide Web Consortium (W3C) XML specifications are part of the stable Internet infrastructure on which all Web services are based.

- Extensible Markup Language (XML) 1.0 - describes a class of data objects called XML documents and partially describes the behaviour of computer programs that process them.
- Namespaces in XML - is a simple method for qualifying element and attribute names used in Extensible Markup Language (XML) documents by associating them with namespaces identified by URI references.
- XML Information Set - provides a consistent set of definitions for use in other specifications that need to refer to the information in a well-formed XML document.
