W3C XML Schema has a formal mechanism for attaching a schema to an XML document, while RELAX NG intentionally avoids such mechanisms for security and interoperability reasons.RELAX NG has no ability to apply default attribute data to an element's list of attributes (i.e., changing the XML info set), while W3C XML Schema does.

Internal DTDs are often supported in XML processors; external DTDs are less often supported, but only slightly.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 the type system of XML processing languages such as XSLT and XQuery (known as "schema-awareness").XML Tools Plugin for Notepad This chapter provides notes and tutorial examples on XML Tools Plugin for Notepad .Topics include downloading and installing Notepad and XML Tools Plugin; generating pretty print XML format; XSD validation; XSLT transformation.Most large XML parsers, ones that support multiple XML technologies, will provide support for DTDs as well.

XSD schemas are conventionally written as XML documents, so familiar editing and transformation tools can be used.

This article explained about the XML document, XSD schema, and how to validate XML document against XSD schema using Microsoft .

When sending data from a sender to a receiver, it is essential that both parts have the same "expectations" about the content.

The process of checking to see if a XML document conforms to a schema is called validation, which is separate from XML's core concept of syntactic well-formedness.

All XML documents must be well-formed, but it is not required that a document be valid unless the XML parser is "validating", in which case the document is also checked for conformance with its associated schema.

There are historic and current XML schema languages: The main ones (see also the ISO 19757's endorsed languages) are described below.
