Demo project with prefixed elements and types in xml

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9.0.8)

Hi

After using a prefix for elements and xsi-types as a workaround in my demo
project, I got another error information:
Unhandled Exception: System.Xml.Schema.XmlSchemaValidationException: XmlSchema
error: Not allowed character content was found. XML  Line 7, Position 111.

The problem is based on empty complex types or complex types containing only
attributes in the XSD file. i.e.
<xs:complexType name="Address"/> or
<xs:complexType name="Address">
  <xs:attribute name="Street" type="xs:string"/>
</xs:comlexType>

-- Workaround --
As a workaround for this problem is to use a dummy element in complex types.
i.e.
<xs:complexType name="Address">
  <xs:sequence>
    <!-- Workaround for Mono to prevent the error "Not allowed character
content was found." in
         XmlSchemaValidatingReader.Read () -->
    <xs:element name="dummy" type="xs:string" minOccurs="0"/>
  </xs:sequence>
  <xs:attribute name="Street" type="xs:string"/>
</xs:complexType>
