XML

This page describes the work being done at W3C within the XML Activity, and how it is structured. Work at W3C takes place in Working Groups. The Working Groups within the XML Activity are listed below, together with links to their individual web pages.

An executive overview of W3C's current and historical work on the Extensible Markup Language (XML).

XML.com features a rich mix of information and services for the XML community. The site is designed to serve both people who are already working with XML and those HTML users who want to "graduate" to XML's power and complexity. A core feature of the site is the Annotated XML Specification, created by Tim Bray, co-editor of XML 1.0 and a contributing editor for XML.com.

W3C document about XML Base

This specification provides a set of definitions for use in other specifications that need to refer to the information in an XML document.

This document specifies XML digital signature processing rules and syntax. XML Signatures provide integrity, message authentication, and/or signer authentication services for data of any type, whether located within the XML that includes the signature or elsewhere.

Any XML document is part of a set of XML documents that are logically equivalent within an application context, but which vary in physical representation based on syntactic changes permitted by XML 1.0 [XML] and Namespaces in XML [Names]. This specification describes a method for generating a physical representation, the canonical form, of an XML document that accounts for the permissible changes. Except for limitations regarding a few unusual cases, if two documents have the same canonical form, then the two documents are logically equivalent within the given application context. Note that two documents may have differing canonical forms yet still be equivalent in a given context based on application-specific equivalence rules for which no generalized XML specification could account.

This document allows a style sheet to be associated with an XML document by including one or more processing instructions with a target of xml-stylesheet in the document's prolog.

The XML standard supports logical documents composed of possibly several entities. It may be desirable to view or edit one or more of the entities or parts of entities while having no interest, need, or ability to view or edit the entire document. The problem, then, is how to provide to a recipient of such a fragment the appropriate information about the context that fragment had in the larger document that is not available to the recipient. The XML Fragment WG is chartered with defining a way to send fragments of an XML document?regardless of whether the fragments are predetermined entities or not?without having to send all of the containing document up to the part in question. This document defines Version 1.0 of the [eventual] W3C Recommendation that addresses this issue.
