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.
