Try:

    <xsd:annotation><xsd:appinfo>
      <jaxb:property generateIsSetMethod="true"/>
    </xsd:appinfo></xsd:annotation>

In you case, it would be:

    <xs:element minOccurs="0" ref="read-only">
      <xsd:annotation><xsd:appinfo>
        <jaxb:property generateIsSetMethod="true"/>
      </xsd:appinfo></xsd:annotation>
    </xs:element>

Or the equivalent external customization.
