http://www.w3.org/ -- 16 November 1999 -- The World Wide Web Consortium
(W3C) today releases two specifications, XSL Transformations (XSLT) and
XML Path Language (XPath), as W3C Recommendations. These new
specifications represent cross-industry and expert community agreement
on technologies that will enable the transformation and styled
presentation of XML documents. A W3C Recommendation indicates that a
specification is stable, contributes to Web interoperability, and has
been reviewed by the W3C membership, who favor its adoption by the industry.
"Anyone using XML can now take advantage of XSLT, a powerful new tool
for manipulating, converting or styling documents," declared Tim
Berners-Lee, W3C Director. "XPath adds a simple way of referring to
parts of an XML document. Together, they strike a fine balance between
simplicity of use and underlying power."
XSLT and XPath Add Strength, Flexibility to XML Architecture
As more content publishers and commercial interests deliver rich data in
XML, the need for presentation technology increases in both scale and
functionality. XSL meets the more complex, structural formatting demands
that XML document authors have.
XSLT makes it possible for one XML document to be transformed into
another according to an XSL Style sheet. As part of the document
transformation, XSLT uses XPath to address parts of an XML document that
an author wishes to transform. XPath is also used by another XML
technology, XPointer, to specify locations in an XML document. "What
we've learned in developing XPath will serve other critical XML
technologies already in development," noted Daniel Veillard, W3C Staff
contact for the XML Linking Working Group.
Together, XSLT and XPath make it possible for XML documents to be
reformatted according to the parameters of XSL style sheets and increase
presentation flexibility into the XML architecture.
Device Independent Delivery of XML Documents
Separating content from presentation is key to the Web's extensibility
and flexibility. "As the Web develops into a structured data space, and
the tools used to access the Web grow more varied, the need for
flexibility in styling and structure is essential," explained Vincent
Quint, W3C User Interface Domain Leader and staff contact for the XSL
Working Group. "With XSLT and XPath, we're closer to delivering rich,
structured data content to a wider range of devices."
Broad Industry Support, Multiple Implementations Already Available
The XSLT Recommendation was written and developed by the XSL Working
Group, which includes key industry players such as Adobe Systems,
Arbortext, Bell Labs, Bitstream, Datalogics, Enigma, IBM, Interleaf,
Lotus, Microsoft, Novell, Oracle, O'Reilly & Associates, RivCom,
SoftQuad Inc, Software AG, and Sun Microsystems. Notable contributions
also came from the University of Edinburgh and a range of invited
The XPath Recommendation pooled together efforts from both the XSL
Working Group and the XML Linking Working Group, whose membership
includes CommerceOne, CWI, DATAFUSION, Fujitsu, GMD, IBM, Immediate
Digital, Microsoft, Oracle, Sun Microsystems, Textuality, and the
University of Southampton.
The creators of XML documents now have a variety of open source and
commercial tools which support XSLT and XPath. In addition, many W3C
members who reviewed the specifications have committed to
implementations in upcoming products, indicated in the wide range of

As an active member of the XSL Working Group, Adobe is very pleased to
see both the XSL Transformations (XSLT) and XML Path Language (XPath)
specifications become official W3C Recommendations. XSLT is an important
tool for mapping XML encoded data and documents into a form suitable for
presentation. We are particularly pleased with the integration of XSLT
patterns and the XPointer referencing mechanism in XPath. This sharing
of technology across
specifications greatly simplifies implementations and usage. Together,
these recommendations will expand the range of XML material that can be
presented on the Web.

Arbortext, Inc., a leading provider of XML-based e-Content software, is
a strong supporter of open standards. With XSLT and XPath,
organizations can target the desired source material and transform the
data to fit that material, thereby enabling the sharing of business
applications among customers and partners. We are excited with the
progress the W3C is making on these XML-related standards and will
continue to work within the W3C for their further development. Arbortext
has included initial support for XSL in its most recent software
release, and we are committed to continuing our support in subsequent
releases as the rest of the XSL work is completed. We are pleased with
the progress the W3C is making toward standards to enable companies to
use XML both to publish information to the Web and as a data interchange
among busines applications.
--Paul Grosso, Vice President of Research, Arbortext, Inc.
We have a vision of an XML-based cross media publishing architecture,
and believe that XSLT is an important step in that direction,
especially for dynamic Web content creation and delivery. We look

RivCom sees the XSLT and XPath specifications as crucially important for
the design and development of the Web-based software applications of the
future. The XML Recommendation opened the way to the storage and
exchange of content as hierarchically structured data. With XPath and
XSLT we now have tools both to navigate and query into that data, and to
transform it. The integration of these and other tools within higher
level tool-sets will enable as yet unheard of possibilities of services
and connectivity on the Web.
RivCom is proud to have participated in the development of these
exciting new possibilities. We have already been putting these
specifications to powerfully effective use within projects such as the
European XML/EDI Pilot Project. The W3C is to be congratulated on
bringing such exciting fruit out of a development process built on the
principles of open information exchange and consensus-based specifications.
