XSL is a language for expressing stylesheets. It consists of two
parts:
-
a language for transforming XML documents, and
-
an XML vocabulary for specifying formatting
semantics.
An XSL stylesheet specifies the presentation of a class of XML
documents by describing how an instance of the class is transformed
into an XML document that uses the formatting vocabulary.
This is a W3C Working Draft for review by W3C members and other
interested parties.
The XSL Working Group considers that this draft is stable and ready
to move to Candidate Recommendation status, following the successful
resolution of comments. This is therefore the
last call for comments on this Working Draft. Please send detailed
comments to xsl-editors@w3.org before 30
April 2000; archives
of the comments are available.
More general public discussion of XSL takes place on the XSL-List
mailing list.
It is a draft document and may be
updated, replaced, or obsoleted by other documents at any time. The
XSL Working Group will not allow early implementation to constrain its
ability to make changes to this specification prior to final release.
It is inappropriate to use W3C Working Drafts as reference material or
to cite them as other than "work in progress". A list of
current W3C working drafts can be found at http://www.w3.org/TR.
This document has been produced as part of the W3C Style Activity by
the XSL Working Group
(members only).
