This specification describes the required behavior of an XML processor in terms of how it must read XML data and the information it must provide to the application." [adapted from the Proposal] Valid XML documents are designed to be valid SGML documents, but XML documents have additional restrictions. Several other W3C specifications are also critical to the understanding and implementation of XML as it is currently used. Editors: Tim Bray (Textuality and Netscape), Jean Paoli (Microsoft), and C. Sperberg-Mc Queen (University of Illinois at Chicago). Obviously, many of these application areas provide exemplary models, having unquestioned integrity and high quality.
The W3C XML WG has published a technical NOTE providing a "detailed comparison of the additional restrictions that XML places on documents beyond those of SGML": see for the details.

Historically: The W3C SGML Editorial Review Board, as of November 5, 1996, had the following members: Jon Bosak, Sun ([email protected]), chair; Tim Bray, Textuality ([email protected]), editor; James Clark ([email protected]), technical lead; Dan Connolly ([email protected]), W3C contact; Steve De Rose, EBT ([email protected]), editor; Dave Hollander, HP ([email protected]); Eliot Kimber, Passage Systems ([email protected]); Tom Magliery, NCSA ([email protected]); Eve Maler, Arbor Text ([email protected]); Jean Paoli, Microsoft ([email protected]); Peter Sharpe, Soft Quad ([email protected]); C. These specifications are being developed by various working groups, sometimes as part of activity outside the sphere of the XML Activity. Some already play a vital role in profitable commercial enterprise.
Such exchange is facilitated by schemas defining the characteristics of classes of objects.
The objects can be syntactic constructs such as are used in XML instances, or may be more abstract such as are found in databases, information models or directed, labeled graphs.
These working groups were designed to have close liaison relationships with the W3C's Extensible Style[sheet] Language (XSL) Working Group and Document Object Model (DOM) Working Group.
"Extensible Markup Language, abbreviated XML, describes a class of data objects called XML documents and partially describes the behavior of computer programs which process them.
XML was initially "developed by a W3C Generic SGML Editorial Review Board formed under the auspices of the W3 Consortium in 1996 and chaired by Jon Bosak of Sun Microsystems, with the very active participation of a Generic SGML Working Group also organized by the W3C." An XML WG (Working Group) under W3C served initially as an editorial board, which received input from an XML Special Interest Group.
It "defines the Document Object Model Level 2, a platform- and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure and style of documents.
It is also expected to find use in certain metadata applications.
