A reference to a sampling feature, for example a diggs:Sounding, that provides theprovenance of a diggs:ProvenancedParameter value. Repeat for several. Do not mixwith diggs:sourceMeasurementRef or diggs:sourceObservationRef on the same parameter.Given by reference only.

It gives an alternative to the gml:id in xlink:href for findingthe referenced feature, mainly to reference a feature by a globallyunique identifier and where naming conflicts occur with gml:id whenaccessing data in external files.
