  XSLT (Extensible Stylesheet Language Transformations) is a W3C standard language for
  transforming XML documents into other formats such as HTML, plain text, or different
  XML structures. It uses template-based rules and XPath expressions to select and
  restructure XML data. The current version is XSLT 3.0, a W3C Recommendation since
  June 2017. XSLT is commonly used in data integration, document publishing, and
  enterprise data exchange pipelines. The primary production implementation is Saxon
  by Saxonica, which supports XSLT 3.0, XQuery 3.1, and XPath 3.1.

      XSLT 3.0 is the current W3C Recommendation for XSL Transformations, published
      June 8, 2017. It introduces streaming support, maps and arrays, higher-order
      functions, improved modularity, and enhanced error handling over XSLT 2.0. The
      specification defines the syntax and semantics of the XSLT language.

      XSLT 2.0 is a W3C Recommendation published January 23, 2007. It significantly
      enhanced XSLT 1.0 with type system integration from XML Schema, grouping,
      multiple result documents, regular expressions, improved string handling, and
      user-defined functions. Second edition published 2009.

    description: >-
      XSLT 1.0 is the foundational W3C Recommendation for XSL Transformations, published
      November 16, 1999. It established the template-based transformation model using
      XPath 1.0 for node selection. XSLT 1.0 is still widely supported by all major
      XML processors and browsers.
