HTML
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It defines the content and structure of web content. It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.
XML
Extensible Markup Language (XML) is a markup language and file format for storing, transmitting, and reconstructing data. It 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.

Extensible HyperText Markup Language
Extensible HyperText Markup Language (XHTML) is part of the family of XML markup languages which mirrors or extends versions of the widely used HyperText Markup Language (HTML), the language in which Web pages are formulated.

JSON
JSON (JavaScript Object Notation, pronounced or ) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of name–value pairs and arrays (or other serializable values). It is a commonly used data format with diverse uses in electronic data interchange, including that of web applications with servers.
TeX
TeX (), stylized as '''', is a typesetting program that was designed and written by computer scientist and Stanford University professor Donald Knuth and first released in 1978. The term now refers to the system of extensions – which includes software programs called TeX engines'', sets of TeX macros, and packages which provide extra typesetting functionality – built around the original TeX language. TeX is a popular means of typesetting complex mathematical formulae; it has been noted as one of the most sophisticated digital typographical systems.

OpenDocument
OpenDocument Format (ODF) for Office Applications, also known as OpenDocument, standardized as ISO 26300, is an open file format for word processing documents, spreadsheets, presentations and graphics using ZIP-compressed XML files. It was developed with the aim of providing an open, XML-based file format specification for office applications.
XSLT
XSLT (Extensible Stylesheet Language Transformations) is a language originally designed for transforming XML documents into other XML documents, or other formats such as HTML for web pages, plain text, or XSL Formatting Objects. These formats can be subsequently converted to formats such as PDF, PostScript, and PNG. Support for JSON and plain-text transformation was added in later updates to the XSLT 1.0 specification.
Standard Generalized Markup Language

XSL
In computing, the term Extensible Stylesheet Language (XSL) is used to refer to a family of languages used to transform and render XML documents (e.g., XSL is used to determine how to display a XML document as a webpage).

VoiceXML
VoiceXML (VXML) is a digital document standard for specifying interactive media and voice dialogs between humans and computers. It is used for developing audio and voice response applications, such as banking systems and automated customer service portals. VoiceXML applications are developed and deployed in a manner analogous to how a web browser interprets and visually renders the Hypertext Markup Language (HTML) it receives from a web server. VoiceXML documents are interpreted by a voice browser and in common deployment architectures, users interact with voice browsers via the public switche

XLink
XML Linking Language, or XLink, is an XML markup language and W3C specification that provides methods for creating internal and external links within XML documents, and associating metadata with those links.
JSON-LD
JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding linked data using JSON and of serializing data similarly to traditional JSON. It is meant to be simple to create by modifying JSON documents. JSON-LD is a World Wide Web Consortium Recommendation initially developed by the JSON for Linking Data Community Group, transferred to the RDF Working Group for review, improvement and standardization, and now maintained by the JSON-LD Working Group.

TOML
'''Tom's Obvious, Minimal Language (TOML, originally Tom's Own Markup Language') is a file format for configuration files. It is designed to be easy to read and write by being minimal'' (unlike the more-complex YAML) and by using human-readable syntax. The project standardizes the implementation of the ubiquitous INI file format (which it has largely supplanted), removing ambiguity from its interpretation. Originally created by Tom Preston-Werner, the TOML specification is open source. TOML is used in a number of software projects and is implemented by all popular programming languages.
XML Binding Language
XML Binding Language (XBL) is an XML-based markup language for altering the behavior of XUL widgets. It was devised at Netscape in the late 1990s as an extension of XUL.

Texinfo
Texinfo is a typesetting syntax used for generating documentation in both on-line and printed form (creating filetypes as , , , etc., and a specific hypertext format, ) with a single source file. It is implemented by a computer program released as free software of the same name, created and made available by the GNU Project from the Free Software Foundation.

XULRunner
XULRunner is a discontinued, packaged version of the Mozilla platform to enable standalone desktop application development using XUL, developed by Mozilla. It replaced the Gecko Runtime Environment, a stalled project with a similar purpose. The first stable developer preview of XULRunner was released in February 2006, based on the Mozilla 1.8 code base. Mozilla stopped supporting the development of XULrunner in July 2015.
