Hi

I have a schema file which has 'persons' as root element.
'persons' has 'person' as child element which has 'Name' as child element.

I declared another element called 'FirstName' which can be substituted to
element 'Name'

Now I need to identify what are all the elements can be substuted in place
of element 'Name'.

In the above example I can use 'FirstName' instede of 'Name' in my XML doc.

Is there any way to get substitution list from XSD parser ?.

Here I am attaching sample schema and XML docs.

Thanks
Param

Family.xsd

<?xml version="1.0" encoding="ISO-8859-1"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.gxs.com" targetNamespace="http://www.gxs.com"
elementFormDefault="qualified">
<xs:element name="person" >
<xs:complexType>
<xs:sequence>
<xs:element ref="Name"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="persons">
<xs:complexType>
<xs:sequence>
<xs:element ref="person" maxOccurs="40" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="Name" type="xs:string"/>
<xs:element name="FirstName" type="xs:string" SubstitutionGroup="Name"/>
</xs:schema>

Family.xml

<?xml version="1.0" encoding="UTF-8"?>

XSDElementDeclaration.getSubstitutionGroup should yield the list of
substitutable element declarations.
