Considering the following schema:

...
    <xs:element name="name" type="xs:string"/>
    <xs:element name="nom" substitutionGroup="myns:name"/>

    <xs:complexType name="person">
        <xs:sequence>
            <xs:element ref="myns:name"/>
        </xs:sequence>
    </xs:complexType>

    <xs:element name="person" type="myns:person"/>
    <xs:element name="personne" substitutionGroup="myns:person"/>
...

Taking this schema and generating EclipseLink mappings, if we set the JAXBElement for "name" to have a QName of "nom", then you will see duplicate elements written to XML, for both the original as well as the substituted name:

<?xml version="1.0" encoding="UTF-8"?>
<ns0:person xmlns:ns0="myNamespace">
   <ns0:name>Bob Smith</ns0:name>
   <ns0:nom>Bob Smith</ns0:nom>
</ns0:person>
