Validating while loop
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.Copyright © 2008 The Extensible Markup Language (XML) is a subset of SGML that is completely described in this document.
XML has been designed for ease of implementation and for interoperability with both SGML and HTML.These terms are by no means standard, although the concepts we present here are typical for web-application testing.Please refer to the errata for this document, which may include some normative corrections.XML provides a mechanism to impose constraints on the storage layout and logical structure.[Definition: A software module called an XML processor is used to read XML documents and provide access to their content and structure.] [Definition: It is assumed that an XML processor is doing its work on behalf of another module, called the application.] 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.Parsed data is made up of characters, some of which form character data, and some of which form markup.
Markup encodes a description of the document's storage layout and logical structure.
W3C maintains a public list of any patent disclosures made in connection with the deliverables of the group; that page also includes instructions for disclosing a patent.
An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) must disclose the information in accordance with section 6 of the W3C Patent Policy.
Most of the errata in the list provide a rationale for the change.
The errata list for this fifth edition is available at A Test Suite is maintained to help assessing conformance to this specification.
