Hi Ollie,
Yes that works, but I was hoping that we could use something more specific 
than a generic xlink:href in order to facilitate the querying.

The previous uom="http://www.opengis.net/def/uom/OGC/1.0/metre" 
potentially allows client software to catch the uom values and send them 
to a UOM vocabulary service to recalculate the values to a common uom. I'm 
not sure the generic solution allows this use-case and is therefore loss 
of functionality.

Cheers
Bruce Simons

Hi Bruce,
 
Try this:
 
    <samsp:positionalAccuracy>
        <gmd:DQ_AbsoluteExternalPositionalAccuracy>
            <gmd:result>
                <gmd:DQ_QuantitativeResult>
                    <gmd:valueUnit xlink:href="
http://www.opengis.net/def/uom/OGC/1.0/metre" xlink:title="m"/>  <!-- href 
to OGC definition for metres -->
                    <gmd:value>
                        <gco:Record>300</gco:Record>  <!-- A string -->
                    </gmd:value>
                </gmd:DQ_QuantitativeResult>
            </gmd:result>
        </gmd:DQ_AbsoluteExternalPositionalAccuracy>
    </samsp:positionalAccuracy>

Hi all, 
I've started generating an instance document for 
http://xmlns.geosciml.org/Borehole/3.0 and run into a UOM problem. 
We have replaced: 
 <sa:surveyDetails> 
        <sa:SurveyProcedure> 
                <sa:positionMethod> 
                        <om:Process> 
                                <gsml20:CGI_TermValue> 
                                        <gsml20:value codeSpace="
http://www.dpi.vic.gov.au/earth-resources">Digitised metric</gsml:value> 
                                </gsml20:CGI_TermValue> 
                        </om:Process> 
                </sa:positionMethod> 
                <sa:positionAccuracy uom="
http://www.opengis.net/def/uom/OGC/1.0/metre">300</sa:positionAccuracy> 
        </sa:SurveyProcedure> 
</sa:surveyDetails>

                                                <gmd:valueUnit> 
                                                        <gml:BaseUnit 
gml:id=""> 
                                                                <
gml:identifier codeSpace=""></gml:identifier> 
                                                                <
gml:unitsSystem></gml:unitsSystem> 
                                                        </gml:BaseUnit> 
                                                </gmd:valueUnit> 
                                                <gmd:value> 
                                                </gmd:value> 
                                        </gmd:DQ_QuantitativeResult> 
                                </gmd:result> 
                        </gmd:DQ_AbsoluteExternalPositionalAccuracy> 
                </samsp:positionalAccuracy>         

The   <gmd:DQ_AbsoluteExternalPositionalAccuracy> property looks 
over-inflated, but I can live with that.  However, I can't see where the 
unit of measure goes. 

Has anyone tried to populate a gmd result and worked out what goes in each 
of these properties?
