Proposed Group: XSLT Extensions Community Group

The XSLT Extensions Community Group has been proposed by Michael Kay:


The group aims to agree extensions to the XSLT 3.0 Recommendation published on 8 June 2017, along with supporting changes to the other specifications (XPath, Functions and Operators) on which it depends.

A preliminary proposal describing requirements for such extensions can be found in Michael Kay’s Proposal for XSLT 4.0 published in the Proceedings of XML Prague 2020

It is intended that the group will operate primarily by use of email and forums but may hold a face-to-face meeting to resolve issues prior to final publication of a specification.

The group may publish specifications.


You are invited to support the creation of this group. Once the group has a total of five supporters, it will be launched and people can join to begin work. In order to support the group, you will need a W3C account.

Once launched, the group will no longer be listed as “proposed”; it will be in the list of current groups.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please send us email on site-comments@w3.org

Thank you,
W3C Community Development Team
