Also, let's remember that a resource could also be the value of a property,
and that is not always the case that URI can be found in a xlink attribute.
For example:

Resource = System, which identification could be the URL of the SensorML
instance
Property = Procedure Type
Value = URI in the sml:value

 <sml:classification>
                <sml:ClassifierList>
                    <sml:classifier name="System Type">
                        <sml:Term definition="
http://www.w3.org/1999/02/22-rdf-syntax-ns#type">
                            <sml:value>
http://mmisw.org/mmi/20080529/sensor.owl#CTD</sml:value>
                        </sml:Term>
                    </sml:classifier>
                </sml:ClassifierList>
            </sml:classification>


And, I think  SensorML and other specs in SWE are not fully compliant with
GML.
