Hi,
i have the following schema structure:

<xs:schema ..... xmlns:c = "http://www.destatis.de/schema/edb/commonType/1.0" .....> 
<xs:import namespace = "...." schemaLocation "commonTypeSchema"></xs:import>
<xs:element name = "organisation"> 
<xs:complexType> 
..... 
<xs:element name = "contact" type = "c:employeeType" minOccurs = "0" maxOccurs = "2"> 
<xs:annotation> 
<xs:appinfo> 
<tsd:elementInfo> 
<tsd:physical> 
<tsd:which>/organisation/contact</tsd:which> 
<tsd:native> 
<tsd:index> 
<tsd:reference></tsd:reference> 
</tsd:index> 
</tsd:native> 
</tsd:physical> 
</tsd:elementInfo> 
</xs:appinfo> 
</xs:annotation> 
</xs:element> 
.......

in the imported schema i defined the employee type:

<xs:complexType name = "employeeType"> 
<xs:sequence> 
<xs:element name = "firstName" type = "xs:string"></xs:element> 
<xs:element name = "lastName" type = "xs:string"></xs:element> 
<xs:element name = "titel" type = "xs:string" minOccurs = "0"></xs:element> 
<xs:element name = "salutation" type = "xs:string"></xs:element> 
<xs:element name = "unit" type = "xs:string"></xs:element> 
<xs:element name = "phone" type = "xs:string"></xs:element> 
<xs:element name = "mobilePhone" type = "xs:string" minOccurs = "0"></xs:element> 
<xs:element name = "fax" type = "xs:string" minOccurs = "0"></xs:element> 
<xs:element name = "email" type = "xs:string"></xs:element> 
</xs:sequence> 
</xs:complexType> 

my question is :
how can i reference to the reference index, which is defined in the importing schema(organisationSchema), in imported schema(commonTypSchema)?

Hi

You may use the following fragment in the imported schema - but you have to assert that wherever employeeType is used it is a descendant node of the referenced node /organisation/contact.
