This document does not define a complete mapping of an XML Schema to an OPC UA Information Model or from an OPC UA Information Model to XML. Different mapping approaches can be used depending on the concrete use cases for such a mapping.
This document defines the bidirectional mapping of XML built-in data types and OPC UA built-in DataTypes. The mappings defined here can be used as the basis for other use cases, even if the mapping strategies on a higher level are different.
If a simple one-way mapping of OPC UA built-in DataTypes to XML is needed then the XML schema defined in OPC 10000-6 should be used instead of the mapping defined here.
