Re: [xml-dev] ANN: How to design an XML Schema component into whichother

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>
