Title: XML Schema generation HowTo
Post by: PeterHeintz on November 03, 2004, 06:00:05 am

I am fiddling around with the XML-Schema generation and I had very quickly some success to design my schema somehow top down.

On the leaves of my tree I get lost. I don’t know how to model e.g.

<xs:element name="Doc.Title" maxOccurs="unbounded">
<xs:complexType>
 <xs:simpleContent>
  <xs:extension base="xs:string">
   <xs:attribute ref="Language" use="required"/>
   <xs:attribute name="Status" use="required">
   <xs:simpleType>
    <xs:restriction base="xs:NMTOKEN">
     <xs:enumeration value="UnderDevelopment"/>
     <xs:enumeration value="Released"/>
     <xs:enumeration value="Obsolete"/>
     <xs:enumeration value="Replaced"/>
    </xs:restriction>
   </xs:simpleType>
   </xs:attribute>
  </xs:extension>
 </xs:simpleContent>
</xs:complexType>
</xs:element>
or in other words just a node containing a text node and two attributes.

Any help is welcome.

I have the same problem.  I created complexType, extended from xsd:string a and attribute added. I got this :

<xs:complexType name="objectclass">
<xs:complexContent>
<xs:extension base="xs:string">
<xs:sequence/>
<xs:attributeGroup ref="objectclass.att"/>
</xs:extension>
</xs:complexContent>
</xs:complexType>

- it is not valid - I need nested simpleContent (insted of complexContent), without empty xs:sequence.
