Hi Roger,
    For the XML example you've written at the document URL, here's
probably another technique (using XML Schema 1.1 assertions and
complexType restriction) to achieve the stated instance validation
objectives:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
                   targetNamespace="http://www.example.org/header"
		   xmlns:header="http://www.example.org/header"
		   elementFormDefault="qualified">

	<xs:element name="Header">
	     <xs:complexType>
	         <xs:complexContent>
		      <xs:restriction base="header:TYPE_BASE">
			    <xs:sequence>
				   <xs:element name="Author" type="xs:string" />
				   <xs:element name="Report"
targetNamespace="http://www.example.org/report"
xmlns:report="http://www.example.org/report">
				          <xs:complexType>
					       <xs:sequence>
					            <xs:any processContents="lax"/>
					       </xs:sequence>
					      <xs:assert test="report:Title"/>
					  </xs:complexType>
				   </xs:element>
			      </xs:sequence>
			</xs:restriction>
		  </xs:complexContent>
	   </xs:complexType>
	</xs:element>
	
	<xs:complexType name="TYPE_BASE">
	    <xs:sequence>
	         <xs:any processContents="lax" maxOccurs="2" />
	    </xs:sequence>
	</xs:complexType>

</xs:schema>
