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.The good news is this: Net users are seeing clearly that a fixed tag set (like HTML) is not the solution. See the references for TEI - the XML version in a separate document, and the section 'Academic Applications' for background on the SGML version of the TEI DTD.

In addition, Web Collections can be expressed inside HTML documents or on their own. Some of the anticipated applications of Web Collections include Web Maps, HTML Email Threading, PIM functions, scheduling, content labeling, and distributed authoring." ["work in progress"] Netscape Communications announced a new proposed XML application.

In addition they are stylistically similar to HTML to enable easy authoring. According to the notice on the Netscape Developer's page: "The Meta Content Framework, or MCF, provides a standard way to describe files or collections of information. According to the introduction, XML-Data "describes an XML vocabulary for schemas, that is, for defining and documenting object classes.

It is also expected to find use in certain metadata applications.

XML is fully internationalized for both European and Asian languages, with all conforming processors required to support the Unicode character set in both its UTF-8 and UTF-16 encodings. Abstract: "The Extensible Markup Language (XML) is a subset of SGML that is completely described in this document.

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.

As of late 1998, the XML design effort was re-chartered under the direction of an XML Coordination Group and XML Plenary Interest Group to be carried out in five new XML working groups: XML Schema Working Group, XML Fragment Working Group, XML Linking Working Group (XLink and XPointer), XML Information Set Working Group, and XML Syntax Working Group.

A software module called an XML processor is used to read XML documents and provide access to their content and structure. Edited by Tim Bray (Textuality and Netscape), Jean Paoli (Microsoft), C. Sperberg-Mc Queen (University of Illinois at Chicago and Text Encoding Initiative), and Eve Maler (Sun Microsystems, Inc. The XML applications and announced industry initiatives listed below have not been evaluated according to any serious criteria for quality and genuineness.

It is assumed that an XML processor is doing its work on behalf of another module, called the application. is the principal document governing the XML standard. Since the various specifications documents for XML/XLink/XSL are still in some flux, it would often be unfair or difficult to make such a judgment.
