Template:Var/doc

This template is to help facilitate the displaying of variable names (in mathematics, computer source code, wikimarkup, etc.) with the semantically correct, which also renders the variable in italics, as is customary. This method is preferred to simply italicizing for many reasons, including accessibility, separation of presentation and content, semantic Web, and metadata; In XHTML and HTML, the <var> element has semantic meaning, while simple italicization does not. "Variable" in this sense may include arbitrary or unknown names or terms, example human input, arithmetical variables in equations, etc.
