For the XSD base64Binary and hexBinary data types, use an array of Byte structures and apply a XmlArrayItemAttribute with the DataType property set to "base64Binary" or "hexBinary", as appropriate. For the XSD time and date data types, use the DateTime type and apply the XmlAttributeAttribute with the DataType set to "date" or "time".

For every XSD type that is mapped to a string, apply the XmlAttributeAttribute with its DataType property set to the XSD type. However, this does not change the serialization format, only the schema for the member.

NoteNote:

The property is case-sensitive, so you must set it exactly to one of the XSD data types.
NoteNote:

Passing binary data as an XML element is more efficient than passing it as an XML attribute.
