Remarks

The Namespace property allows you to set a unique name for the XML attribute. The Namespace property conforms to the rules for creating an XML namespace as found in the Namespaces in XML document from the World Wide Web Consortium.

To set the Namespace property to a prefixed name, create an XmlSerializerNamespaces that contains the namespaces and prefixes used in the XML document. Set the Namespace property to one of the namespaces in the XmlSerializerNamespaces. When the XML is generated, the attribute name is correctly prefixed with the prefix associated with the specified namespace.
