RE: Mixed content and empty content

Thanks for the example, but I'm yet more confused.
What is the meaning of a simpleType child to restriction when restriction has a base attribute?

Thanks.

This _is_ allowed -- it's how the simple types are in principle
derivable from anyType.  For your example:

    <xs:complexType name="rtype" mixed="true"/>

    <xs:element name="root">
     <xs:complexType>
      <xs:simpleContent>
       <xs:restriction base="rtype">
        <xs:simpleType>
         <xs:restriction base="xs:integer"/>
        </xs:simpleType>
       </xs:restriction>
      </xs:simpleContent>
     </xs:complexType>
    </xs:element>
