The XML Schema Working Group is closed, having completed its work successfully. The specifications are now maintained by the W3C XML Core Working Group.
Tools · Usage · Resources · Specifications and Development
XML Schemas express shared vocabularies and allow machines to carry out rules made by people. They provide a means for defining the structure, content and semantics of XML documents. in more detail. XML Schema 1.0 was approved as a W3C Recommendation on 2 May 2001 and a second edition incorporating many errata was published on 28 October 2004; see reference list for pointers.
The XML Schema Working Group, part of the XML Activity, is responsible for the W3C's work on this topic -- for details see the Working Group's charter. W3C Members can also participate in the W3C XML Schema Interest Group, a forum for the discussion of technical issues relating to the development of XML Schema.
See also: Robin Cover's index of XML Schema materials.
XML Schema 1.1 (in two parts) is a W3C Recommendation. It is intended to be mostly compatible with XML Schema 1.0 and to have approximately the same scope, but also to fix bugs and make whatever improvements we can, consistent with the constraints on scope and compatibility.
XML Schema 1.1 Part 2: Datatypes and XML Schema 1.1 Part 1: Structures are available.
There is also a Test Collection aimed at determining which parts of XSD 1.1 have been implemented; several implementations are under development.
If you find errors in Schema 1.1, please let us know. The best way to do that is to add an entry to the W3C's public installation of Bugzilla, which the WG uses to track issues and enhancement requests, specifying "XML Schema" as the 'product' name. Full instructions can be found at http://www.w3.org/XML/2006/01/public-bugzilla. If access to Bugzilla is not feasible, please send your comments to the W3C XML Schema Working Group's public comments mailing list, www-xml-schema-commentsAw3.org (archive). Please note that both the Bugzilla installation and the comments list are not only public-write but also public-read; don't say things you don't want seen in public. Each Bugzilla entry and email message should contain only one comment.
The Bugzilla system should also be used to report errors with XML Schema 1.0.
Thanks!
Please send any related announcements to xmlschema-dev.

CodeSynthesis XSD 3.0.0 - Open-source XML Schema to C++ compiler Boris Kolpackov 2007-08-01
CodeSynthesis XSD is an open-source, cross-platform W3C XML Schema to C++ data binding compiler. Provided with a schema, it generates C++ classes that represent the given vocabulary as well as parsing and serialization code. You can then access the data stored in XML using types and functions that semantically correspond to your application domain rather than dealing with elements, attributes, and text in a direct representation of XML such as DOM or SAX.
XSD supports both in-memory and stream-oriented processing models by implementing two C++ mappings: C++/Tree and C++/Parser. The C++/Tree mapping represents the information stored in XML instance documents as a tree-like, in-memory object model. The C++/Parser mapping generates parser skeletons for data types defined in XML Schema. Using these parser skeletons you can build your own in-memory representations or perform immediate processing of XML documents.
XSD is available on AIX, GNU/Linux, HP-UX, Mac OS X, Solaris, and Windows. Supported C++ compilers include: GNU g++, HP aCC, Intel C++, Sun C++, IBM XL C++, and MS Visual C++. More information as well as precompiled binaries for all supported platforms are available from http://www.codesynthesis.com/products/xsd/
CodeSynthesis XSD/e 2.0.0 released Boris Kolpackov 2007-11-13
CodeSynthesis XSD/e is an open-source XML parser/serializer generator for mobile and embedded systems. It provides event-driven, stream-oriented XML parsing, XML serialization, XML Schema validation, and C++ data binding while maintaining a small footprint and portability.
Compared to general-purpose validating XML processors, the XSD/e-generated code is 2-10 times faster while maintaining the lowest static and dynamic memory footprints. For example, a validating parser executable can be as small as 120KB in size. XSD/e is also highly-portable and can be used without STL, RTTI, iostream, C++ exceptions, and C++ templates.
Supported embedded toolchains include GNU g++ 2.95.x-4.x.x, eMbedded Visual C++ 4.0, and Visual Studio 2005 with Smart Devices support. Precompiled binary distributions are available for GNU/Linux, Solaris, and Windows host development platforms.

LINQ to XSD Preview Alpha 0.1 released to the web Ralf Lämmel 2006-11-27
LINQ to XSD is the code name of an incubation project that aims to provide .NET developers with support for typed XML programming on top of LINQ to XML. While the LINQ to XML programmer operates on generic XML trees, the LINQ to XSD programmer operates on typed XML trees -- instances of .NET types that model the XML types of a specific XML schema (XSD). LINQ to XSD can be used whenever you have an XML schema available, or you are willing to infer a schema from the XML data at hand. LINQ to XSD is integrated into Visual Studio; so you just tag an XML schema as an 'LINQ to XSD schema', build your project, and the automatically derived object model is then part of your solution -- just as if XML schemas were .NET types. The derived object model enforces various validation constraints imposed by the underlying XML schema. See http://blogs.msdn.com/xmlteam/archive/2006/11/27/typed-xml-programmer-welcome-to-linq.aspx

Visual XML Schemas Siva Dirisala 2008-01-06
Even though many of the XML Schemas are meant for functional users so that they can design new systems or map existing systems to be standards compliant, their complexity makes it difficult for these users to study them. Even many software developers have difficulty understanding the XML Schemas due to their complexity. Visual Schema addresses this problem by presenting the XML Schemas as familiar and easily navigable html forms, typically found in enterprise business applications, that help the users easily understand the structure of an XML document.
Serveral open standards such as OAGIS and publicly available web services such as Amazon Web Services are available as Visual XML Schemas at http://www.visualschema.com/

XSD regex-> Java 1.4 regex, James Clark 2002-04-30
I've written some Java code that translates from the syntax of XSD regexes to the syntax of JDK 1.4 java.util.regex regexes. The source, binaries and documentation can be downloaded from: [http://www.thaiopensource.com/download/xsdregex-20020430.zip]
I am releasing it under a very liberal license (the BSD license), which makes it free even for commercial use.
xsd - a W3C XML Schema to C++ translator Boris Kolpackov 2005-10-08
xsd is a cross-platform, open source W3C XML Schema to C++ translator. It supports two C++ mappings: in-memory C++/Tree and event-driven C++/Parser.
The C++/Tree mapping consists of data types that represent the given vocabulary, a set of parsing functions that convert XML instance documents to a tree-like in-memory data structure, and a set of serialization functions that convert the in-memory representation back to XML.
The C++/Parser mapping provides parser templates for data types defined in XML Schema. Using these parser templates you can build your own in-memory representations or perform immediate processing of XML instance documents.

The xsdvalid distribution contains the XML Schema validation engine that will be integrated into the future XMLmind XML Editor product ( http://www.xmlmind.com/xmleditor/ ).
This engine has been made available to schema and DTD authors in the form of 3 command-line tools:
The xsdvalid distribution can be downloaded from [http://www.xmlmind.com/xvalid.html] .

Note that there is no longer an XML Schema Working Group to monitor issues or pull requests.
As part of the process of getting XML Schema to Recommendation, a draft Type Library is available, with definitions of complex types attempting to cover many common needs, including general text content, arrays, complex numbers and dimensioned quantities.
Richard Tobin and Henry S. Thompson have posted a first cut at an XML serialisation of the (PSV) Infoset.
XML Schema Part 0: Primer is a non-normative document intended to provide an easily readable description of the XML Schema facilities, and is oriented towards quickly understanding how to create schemas using the XML Schema language. XML Schema Part 1: Structures and XML Schema Part 2: Datatypes provide the complete normative description of the XML Schema language. This primer describes the language features through numerous examples which are complemented by extensive references to the normative texts.

Developments in the community
The W3C workshop on XML Schema user experiences gathered concrete reports of user experience with XML Schema 1.0, and examined the full range of usability, implementation, and interoperability problems around the specification and its test suite.
The Call for Participation and program have many of the details.
Minutes and a chairs' report are expected to be made public real soon now.
