      <p>Ok.</p>
      <p>BTW, I think I will just drop the idea of NativeReference as a
        superclass of Reference, I don't think I can untangle Reference
        and ControlledVocabularyEntry in any meaningful way, this
        requires more thinking than the one it can be done before the
        release. <br>
      </p>
      <p>I just want a simple mechanism to reference an object and its
        type. How about just using Identifier? It doesn't include the
        type, but it's not necessary in the particular case of the
        Process model since it can refer to any identifiable object. It
        will be something like this:</p>

                          <p>Hi, </p>
                          <p>These are the new Native classes, with the
                            old classes as extensions:</p>
                          <p><img id="yiv7610018151Picture_x0020_1"
                              style="width:7.4791in;min-height:4.0138in;"
                              src="cid:QQ8fjXDNjod1aLaXUUp1"
                              yahoo_partid="1.3" moz-do-not-send="true"
                              width="718" height="385" border="0"></p>
                          <p>We can always define attributes of type
                            NativeControlledVocabularyEntry and
                            NativeReference, which will allow us to use
                            the full-fledged list of attributes from the
                            sub-classes if necessary. </p>
                          <p>With that in mind:</p>
                          <p>1) shouldn't we then change the type of the
                            attributes in PairedControlledVocabulary to
                            NativeControlledVocabularyEntry?</p>
                          <p><img id="yiv7610018151Picture_x0020_2"
                              style="width:3.7013in;min-height:1.8125in;"
                              src="cid:TrzQ0zxfh0uzWGWCnox9"
                              yahoo_partid="1.4" moz-do-not-send="true"
                              width="355" height="174" border="0"></p>
                          <p>2) What's exactly "vocabulary" in
                            ControlledVocabularyEntry? How is it used?</p>
                          <p>3) Actually, how do we really use these
                            things? I understand how the Native classes
                            work, but now it seems Reference might be
                            used to reference a term and an extent, like
                            PairedControlledVocabularyEntry, but in a
                            different way. I think there was an example
                            somewhere that help people made sense of all
                            this, but I can't find it, and I fear we are
                            making a mistake somewhere... So many cross
                            references between classes are making me
                            dizzy...</p>
                          <p>Thanks,</p>
                          <p>Flavio</p>
