Presentation semanticsIn computer science, particularly in human-computer interaction, presentation semantics specify how a particular piece of a formal language is represented in a distinguished manner accessible to human senses, usually human vision. For example, saying that ... must render the text between these constructs using some bold typeface is a specification of presentation semantics for that syntax. Many markup languages, including HTML, DSSSL, and XSL-FO, have presentation semantics, but others, such as XML, do not.
