Definitions Overview:

XML (Extensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human–readable and machine–readable. The World Wide Web Consortium’s XML 1.0 Specification of 1998 and several other related specifications – all of them free open standards – define XML. The design goals of XML emphasize simplicity, generality, and usability across the Internet. It is a textual data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, the language is widely used for the representation of arbitrary data structures such as those used in web services. Several schema systems exist to aid in the definition of XML–based languages, while programmers have developed many application programming interfaces (APIs) to aid the processing of XML data.

XSD (XML Schema Definition), a recommendation of the World Wide Web Consortium (W3C), specifies how to formally describe the elements in an Extensible Markup Language (XML) document. It can be used by programmers to verify each piece of item content in a document. They can check if it adheres to the description of the element it is placed in. Like all XML schema languages, XSD can be used to express a set of rules to which an XML document must conform in order to be considered valid according to that schema. However, unlike most other schema languages, XSD was also designed with the intent that determination of a document’s validity would produce a collection of information adhering to specific data types. Such a post–validation infoset can be useful in the development of XML document processing software.
