Mapping Atomic Types to CLR Types: XmlPrime

Overview

This document explains the types that are used to represent atomic values in XmlPrime. In particular these are the types that are used in the TypedValue TypedValue TypedValue and ValueType ValueType ValueType properties on the XPathAtomicValue XPathAtomicValue XPathAtomicValue class.

The types exposed for atomic values in XmlPrime differ from those used in the System.Xml System.Xml System.Xml namespace. In some places we have used different types because the types used in the System.Xml System.Xml System.Xml namespace do not fully represent the value (for example the lack of time zones in the date and time types). In other cases we have used the base type to represent values, for example using decimal Decimal decimal instances to represent xs:int instances. This may change in a future version to be more in line with the .NET types.

Note

This document only applies to atomic values, and does not apply to XPathNavigator XPathNavigator XPathNavigator instances. This is because the XPathNavigator.TypedValue XPathNavigator.TypedValue XPathNavigator::TypedValue property is computed from the schema type by the System.Xml.Schema System.Xml.Schema System.Xml.Schema classes. The types of the values on XPathNavigator XPathNavigator XPathNavigator instances is defined by Mapping XML Data Types to CLR Types.

Note

The types below may change in future versions of XmlPrime. In particular the bindings for the subtypes of xs:integer may be changed to bring them in line with those used by the System.Xml System.Xml System.Xml classes.
