[castor-dev] Making sure id's defined via xsd:ID are unique

[Ibtsam Mahfouz]

Hi

 I am defining a description file for my schema and I want to enforce unique id's. I defined an element as follows in the schema file:

 

<xsd:element name="Settings">
 <xsd:complexType>
  <xsd:sequence>
   <xsd:element ref="ScalarSetting" minOccurs="0" maxOccurs="unbounded"/>
  </xsd:sequence>
 </xsd:complexType>
</xsd:element>

<xsd:element name="ScalarSetting">
 <xsd:complexType>
    <xsd:attributeGroup ref="scalarAttributes"/>
 </xsd:complexType>
</xsd:element>

 

<xsd:attributeGroup name="scalarAttributes">
 <xsd:attribute name="name" type="xsd:string" use="required"/>
  <xsd:attribute name="eid" type="xsd:ID" use="required"/>
</xsd:attributeGroup>

 

I would like all ScalarSettings defined in a file to have a unique id (eid). When I run the above schema through sourceGenerator it generates the java files. I then compile them and then have a test program that calls unmarshall on a file that has the following:

 

<Settings>
   <ScalarSetting name="NameX" eid="151" type="String"/>
   <ScalarSetting name="NameY" eid="151" type="String" />
</Setting
  

I would like the above example to fail because I have two ScalarSetting items with the same eid "151". However, it succeeds. Is there a way to enforce that each value for an eid only appears once in the file (using xsd:ID or some other alternative)?

 

Thanks
