Incorrect XML Schema (incorrect_0.xsd)


<xsd:schema finalDefault="#all" xmlns:xsd="http://www.w3.org/2001/XMLSchema" >

  <xsd:element name="root" type="AAA"/>

  <xsd:simpleType name="AAA">
    <xsd:restriction base="xsd:integer">
      <xsd:minInclusive value="0"/>
    </xsd:restriction>
  </xsd:simpleType>

  <xsd:simpleType name="BBB">
    <xsd:restriction base="AAA">
      <xsd:minInclusive value="10"/>
    </xsd:restriction>
  </xsd:simpleType>
</xsd:schema>

Incorrect XML Schema (incorrect_0.xsd)


<xsd:schema finalDefault="restriction" xmlns:xsd="http://www.w3.org/2001/XMLSchema" >

  <xsd:element name="root" type="AAA"/>
