'''EXSLT''' is a community initiative to provide extensions to [[XSLT]],<ref>{{Cite web |date=2023-07-10 |title=EXSLT {{!}} MDN |url=https://developer.mozilla.org/en-US/docs/Web/EXSLT |access-date=2024-09-26 |website=developer.mozilla.org |language=en-US}}</ref><ref>{{Cite web |title=EXSLT Dates and Times module |url=https://www.ibm.com/docs/en/datapower-gateway/10.6.0?topic=extensions-exslt-dates-times-module |access-date=2024-09-26 |website=www.ibm.com |language=en-us}}</ref> which are broken down into a number of modules, listed below.

The creators (Jeni Tennison, Uche Ogbuji, Jim Fuller, Dave Pawson, et al.) of EXSLT aim to encourage the implementers of XSLT processors to use these extensions, in order to increase the portability of [[style sheet (web development)|stylesheets]].
