XML Technology and Customized Markup Languages

XML Technology employs three languages: XML. The extensible markup language specifies the base syntax of documents and data type definitions (DTDs). XSL. The extensible stylesheet language specifies the appearance of a document. XLL. The extensible linking language specifies links among documents (e.g., associates semantics to a link; define a link that connects more than two resources; define a bidirectional link). Note. The specification of a documents contents (XML) is completely separated from the formatting instructions (XSL). Customized Markup Languages MathML. Markup of mathematical expressions. WML. The wireless markup language allows text portions of web pages to be displayed in wireless devices. XBRL. The extensible business reporting language (XBRL) facilitates creation, exchange and validation of financial information (e.g., annual budgets, dividends). PDML. The product data interchange language is for businesses and government agencies. See http://www.pdml.org . aecXML. See http://www.aecxml.org .
