Please refer to the errata for this document, which may include some normative corrections.The previous errata for this document, are also available. This document is also available in these non-normative formats: XML and XHTML with color-coded revision indicators.Note that most Web browsers don't actually use an SGML parser, many of them display the documents differently based on the document's to your document.

The Error Handler used for the examples is a very simple one which reports the error to and continues until the XML document has been fully parsed or until a fatal-error has been reported.

Namespaces have been introduced to XML after the first specification of XML had received the official W3C Recommendation status.

Copyright © 2008 The Extensible Markup Language (XML) is a subset of SGML that is completely described in this document.

Its goal is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML.

Briefly a DTD defines all the possible elements to be found within your document, what is the formal shape of your document tree (by defining the allowed content of an element; either text, a regular expression for the allowed list of children, or mixed content i.e. The DTD also defines the valid attributes for all elements and the types of those attributes.

The W3C XML Recommendation (Tim Bray's annotated version of Rev1):(unfortunately) all this is inherited from the SGML world, the syntax is ancient... The rules to build them if you need something permanent or something which can evolve over time can be radically different.This task supports the use of nested element is used to set properties.These properties are defined here for the xerces XML parser implementation : XML Parser properties Properties can be used to set the schema used to validate the XML file. The schemavalidate task is better for validating W3C XML Schemas, as it extends this task with the right options automatically enabled, and makes it easy to add a list of schema files/URLs to act as sources.— that is, a language for writing markup languages.HTML is a markup language written in SGML — an "SGML application", to use the terminology.This is the reason why (most of the) XML parser implementations do not support XML Namespaces by default, to handle the validation of XML documents with namespaces correctly it is therefore necessary to configure the underlying parsers to provide support for XML Namespaces.
