    It’s because it doesn’t expect more than one element in your <xs:choice> within your definition of <xs:complexType name="ItemType">. Change that to <xs:choice minOccurs="0" maxOccurs="unbounded"> to fix the first error. You’ll find another similar error after that, in the definition of <Track>. Change that to <xs:element name="Track" minOccurs="0" maxOccurs="unbounded"> and all should be well.
