No, this won't work. We don't generate a template for ref_T which
can later be specialized with a referenced type. This, however, will
work:

<xs:complexType name="ref_to_some_type_T">
  <xs:simpleContent>
    <xs:extension base="xs:IDREF" xse:refType="some_type_T">
      <xs:attribute name="extra_param" type="xs:integer" />
    </xs:extension>
  </xs:simpleContent>
</xs:complexType>

<xs:complexType name="option_T">
  <xs:choice>
    <xs:element name="reference" type="ref_to_some_type_T"/>
  </xs:choice>
</xs:complexType>
