Summary: PNG schema - additional metadata element in multipage schema

Initial Comment:
Testing Branch Xena 5.0.0.

I'm currently working on documenting the XML schemas for the various file formats we support. I'm looking at .xena files and deriving a schema from the XML. In this case I am then comparing the derived schemas for png and multipage png.

The derived schema extract for png is:

                         <xsd:element name="png:png">
                            <xsd:complexType>
                              <xsd:attribute name="png:description" type="xsd:string" />
                              <xsd:attribute name="png:extension" type="xsd:string" />
                            </xsd:complexType>
                          </xsd:element>

As part of multipage file, the derived extract includes an additional element of  <xsd:element name="png:metadata" type="xsd:string" />:

                     <xsd:element name="multipage:multipage">
                            <xsd:complexType>
                              <xsd:sequence>
                                <xsd:element name="multipage:page">
                                  <xsd:complexType>
                                    <xsd:sequence>
                                      <xsd:element name="png:png">
                                        <xsd:complexType>
                                          <xsd:sequence>
                                            <xsd:element name="png:metadata" type="xsd:string" />
                                          </xsd:sequence>
                                          <xsd:attribute name="png:description" type="xsd:string" />
                                        </xsd:complexType>
                                      </xsd:element>
                                    </xsd:sequence>
                                  </xsd:complexType>
                                </xsd:element>
                              </xsd:sequence>
                            </xsd:complexType>
                          </xsd:element>

Should the PNG schema include the  <xsd:element name="png:metadata" type="xsd:string" /> element or should the multipage schema have it removed?
