Hi Folks,

Hopefully there are some Xerces developers on this mailing list (hey Mukul).

The below schema validates fine in Saxon but Xerces throws an error.  /Roger

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    
    <xs:element name="A" type="xs:double" />
    <xs:element name="B" substitutionGroup="A" type="xs:double" />
    
    <xs:complexType name="base">
        <xs:sequence>
            <xs:element ref="A" minOccurs="0" maxOccurs="unbounded" />
        </xs:sequence>
    </xs:complexType>
    
    <xs:complexType name="derived">

                    <xs:element ref="B" minOccurs="0" />
