XML DataType Mapping

Defines mechanisms for a bidirectional mapping of built-in data types between OPC UA and XML. Some data types can directly be mapped in a lossless manner, for others the limitations are described.
The document defines specific OPC UA DataTypes for built-in XML data types that cannot directly be mapped and refers to an XML Schema for OPC UA DataTypes that cannot directly be mapped.

The intended use is for a bidirectional mapping, not just from OPC UA to XML. In such a case, the XML schema defined in OPC 10000-6 should be used.
