XML Schema
From BC$ MobileTV Wiki
XML Schema Definition (commonly abbreviated XSD) is an XML-based document definition format which defines the structure of an XML document. It was introduced by the W3C as an alternative to DTDs in 2001.[1]

Specifications
- XML Schema spec: http://www.w3.org/XML/Schema
- XML Schema instance (usually prefixed as xsi namespace): http://www.w3.org/2001/XMLSchema-instance
- W3C Specification of XML Schema (datatypes): http://www.w3.org/TR/xmlschema-2/
Data Types
XML Schema differs from DTD primarily through the use of strong typing of data, with a large number of datatypes commonly used in modern programming languages, such as string, integer, date and time.
