[xsd] Il validatore mi dà errore

[Stemby]

Buonasera,
qualcuno sa spiegarmi perché il validatore mi dà il seguente errore?

Validation stopped at line 5, column 85: Invalid child 'element' in the complex type

Lo stesso XML Schema scritto in un modo un po' più leggibile:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

  <xsd:element name="transcript">
    <xsd:complexType>

        <xsd:element name="exam" type="examType" minOccurs="0" maxOccurs="unbounded" />
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>

  <xsd:complexType name="examType">
    <xsd:sequence>
      <xsd:element name="credits" type="xsd:positiveInteger" />
      <xsd:element name="date" type="xsd:date" />
      <xsd:element name="mark">
        <xsd:complexType>
          <xsd:simpleContent>
            <xsd:extension base="xsd:positiveInteger">
              <xsd:attribute name="cumLaude" type="xsd:boolean" default="0" />
            </xsd:extension>
          </xsd:simpleContent>
        </xsd:complexType>
      </xsd:element>
    </xsd:sequence>
    <xsd:attribute name="title" type="xsd:string" />
  </xsd:complexType>

</xsd:schema>
