XSLT

A W3C standard language for transforming XML documents into other formats such as HTML, plain text, or different XML structures. XSLT uses template rules that match patterns in the source XML and produce corresponding output, enabling the separation of content from presentation. In accessibility, XSLT is significant because it allows the same structured content to be automatically transformed into different accessible formats — for example, converting a single XML data source into a visual web page for sighted users, a linearized text version for screen readers, a simplified layout for users with cognitive disabilities, or a Braille-optimized format. This transformation capability supports the principle that content should be adaptable to diverse user needs without requiring separate authoring for each format.
