As well as validation, XSD allows XML instances to be annotated with type information (the Post-Schema-Validation Infoset (PSVI)) which is designed to make manipulation of the XML instance easier in application programs. This may be by mapping the XSD-defined types to types in a programming language such as Java ("data binding") or by enriching ...
Schematron schemas are suitable for use in XML Pipelines, thereby allowing workflow process designers to build and maintain rules using XML manipulation tools. The W3C's XProc pipelining language, for example, has native support for Schematron schema processing through its "validate-with-schematron" step. [4]
The tool "xjc" can be used to convert XML Schema and other schema file types (as of Java 1.6, RELAX NG, XML DTD, and WSDL are supported experimentally) to class representations. [3] Classes are marked up using annotations from javax.xml.bind.annotation.* namespace, for example, @XmlRootElement and @XmlElement.
XML validation is the process of checking a document written in XML (eXtensible Markup Language) to confirm that it is both well-formed and also "valid" in that it follows a defined structure. A well-formed document follows the basic syntactic rules of XML, which are the same for all XML documents. [ 1 ]
RELAX NG compact syntax is a non-XML format inspired by extended Backus–Naur form and regular expressions, designed so that it can be unambiguously translated to its XML counterpart, and back again, with one-to-one correspondence in structure and meaning, in much the same way that Simple Outline XML (SOX) relates to XML.
In computing, the Java API for XML Processing (JAXP) (/ ˈ dʒ æ k s p iː / JAKS-pee), one of the Java XML application programming interfaces (APIs), provides the capability of validating and parsing XML documents. It has three basic parsing interfaces: the Document Object Model parsing interface or DOM interface
XML Schema, also referred to as XML Schema Definition (XSD), has achieved Recommendation status within the W3C, [8] and is popular for "data oriented" (that is, transactional non-publishing) XML use because of its stronger typing and easier round-tripping to Java declarations.
RELAX NG has a simpler definition and validation framework than XML Schema, making it easier to use and implement. It also has the ability to use datatype framework plug-ins; a RELAX NG schema author, for example, can require values in an XML document to conform to definitions in XML Schema Datatypes.
