    All,

    I discovered this new issue recently. The Server element definition in
    PwgSemanticModel.xsd does not have an extension point as do all the other
    elements. The result is that we would be unable to add any other services
    such as scan or any device to the root node.

    The incorrect (i.e. current) definition is
    <xsd:complexType name="Server">
                    <xsd:annotation>
                            <xsd:documentation>The container object Server is
    not explicitly modeled in the PWG Semantic Model</xsd:documentation>
                    </xsd:annotation>
                    <xsd:sequence>
                            <xsd:element name="Printer" maxOccurs="unbounded">
                                    <xsd:complexType>
                                            <xsd:complexContent>
                                                    <xsd:extension
    base="Printer">
                                                            <xsd:sequence>
                                                                    <xsd:element
    name="Job" minOccurs="0" maxOccurs="unbounded">
            
    <xsd:complexType>
            
    <xsd:complexContent>
            
    <xsd:extension base="Job">
            
    <xsd:sequence>
            
    <xsd:element name="Document" type="Document" minOccurs="0"
    maxOccurs="unbounded"/>
            
    </xsd:sequence>
            
    </xsd:extension>
            
    </xsd:complexContent>
            
    </xsd:complexType>
            
    </xsd:element>
                                                            </xsd:sequence>
                                                    </xsd:extension>
                                            </xsd:complexContent>
                                    </xsd:complexType>
                            </xsd:element>
                    </xsd:sequence>
            </xsd:complexType>

    The correct definition is
    <xsd:complexType name="Server">
                    <xsd:annotation>
                            <xsd:documentation>The container object Server is
    not explicitly modeled in the PWG Semantic Model</xsd:documentation>
                    </xsd:annotation>
                    <xsd:sequence>
                            <xsd:element name="Printer" maxOccurs="unbounded">
                                    <xsd:complexType>
                                            <xsd:complexContent>
                                                    <xsd:extension
    base="Printer">
                                                            <xsd:sequence>
                                                                    <xsd:element
    name="Job" minOccurs="0" maxOccurs="unbounded">
            
    <xsd:complexType>
            
    <xsd:complexContent>
            
    <xsd:extension base="Job">
            
    <xsd:sequence>
            
    <xsd:element name="Document" type="Document" minOccurs="0"
    maxOccurs="unbounded"/>
            
    </xsd:sequence>
            
    </xsd:extension>
            
    </xsd:complexContent>
            
    </xsd:complexType>
            
    </xsd:element>
                                                            </xsd:sequence>
                                                    </xsd:extension>
                                            </xsd:complexContent>
                                    </xsd:complexType>
                            </xsd:element>
                            <xsd:any namespace="##any" minOccurs="0"
    maxOccurs="unbounded"/>
                    </xsd:sequence>
            </xsd:complexType>

    The proposal is to replace the incorrect definition in PwgSemanticModel.xsd
    with the correct one. I will bump the minor version number of the schema
    file.

    Please send out a note to the mailing list if you have any objections to
    this change.
