Answer the following question: Information:  - In computing, Extensible Markup Language (XML) 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 W3C's XML 1.0 Specification and several other related specificationsall of them free open standardsdefine XML.  - Query languages are computer languages used to make queries in databases and information systems.  - The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web (abbreviated WWW or W3).  - XPath 2.0 is a version of the XPath language defined by the World Wide Web Consortium , W3C . It became a recommendation on 23 January 2007 . As a W3C Recommendation it was superseded by XPath 3.0 on 10 April 2014 . XPath is used primarily for selecting parts of an XML document . For this purpose the XML document is modelled as a tree of nodes . XPath allows nodes to be selected by means of a hierarchic navigation path through the document tree . The language is significantly larger than its predecessor , XPath 1.0 , and some of the basic concepts such as the data model and type system have changed . The two language versions are therefore described in separate articles . XPath 2.0 is used as a sublanguage of XSLT 2.0 , and it is also a subset of XQuery 1.0 . All three languages share the same data model ( the XDM ) , type system , and function library , and were developed together and published on the same day .  - A standards organization, standards body, standards developing organization (SDO), or standards setting organization (SSO) is an organization whose primary activities are developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise producing technical standards that are intended to address the needs of a group of affected adopters.  - XPath (XML Path Language) is a query language for selecting nodes from an XML document. In addition, XPath may be used to compute values (e.g., strings, numbers, or Boolean values) from the content of an XML document. XPath was defined by the World Wide Web Consortium (W3C).  - The World Wide Web (abbreviated WWW or the Web) is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989. He wrote the first web browser computer program in 1990 while employed at CERN in Switzerland.    Given the information above, choose from the list below the object entity that exhibits the relation 'instance of' with the subject 'xpath 2.0'.  Choices: - computer  - consortium  - document  - encoding  - format  - group  - human  - information  - language  - organization  - path  - query language  - resource  - set  - standards organization  - xml
Answer:
query language
