XSD Tutorials - Herong's Tutorial Examples - Version 5.10, by Dr. Herong Yang

Introduction of XSD Built-in Datatypes

This chapter provides notes and tutorial examples on built-in datatypes defined in XML Schema 1.1. Topics include complete list of built-in datatypes, using built-in datatypes to declare XML elements and attributes; special built-in datatypes 'anyType', 'anySimpleType', 'anyAtomicType'.

Overview of XSD 1.1 Built-in Datatypes

List of Built-in Datatypes

Datatypes, Values and Representations

Datatypes, Values and Representations - Example

Built-in Datatypes Lexical Representation Examples

Declaring Elements and Attributes with Built-in Datatypes

Defining New Datatypes with Built-in Datatypes

"anyType" Built-in Datatype Values and Representations

"anySimpleType" Built-in Datatype Values and Representations

"anyAtomicType" Built-in Datatype Values and Representations

Conclusion:

  • There are 50 built-in datatypes supported in XSD 1.1. 4 new built-in datatypes are introduced in XSD 1.1: anyAtomicType, dateTimeStamp, dayTimeDuration and yearMonthDuration.
  • There are 3 special built-in types: anyType, anySimpleType and anyAtomicType, which are acting like base datatypes for other built-in datatypes.
  • All built-in datatypes, except anyType, are simple types that can be used to declare both XML elements and attributes.
  • anyType is a complex type which can only be used to declare XML elements.
  • JDK 1.7 only supports XML Schema 1.0 (XSD 1.0) validation, not XSD 1.1.
  • "Xerces2 2.11.0 (XML Schema 1.1) (Beta)" version supports XSD 1.1 validation.
  • The value space of a datatype is the set of values that are supported by that datatype.
  • The lexical space of a datatype is the prescribed set of strings which can be mapped to values of that datatype.
  • A lexical representation is single item in the Lexical Space.
