A reference to a measurement, a test or a monitoring reading, that provides theprovenance of a diggs:ProvenancedParameter value. Repeat where a value derives frommore than one measurement, for example a correlation drawing on several tests. Donot mix with diggs:sourceObservationRef or diggs:sourceSamplingFeatureRef on thesame parameter; use one kind of source. Given by reference only.
The gml:identifier value of the referenced feature, as a fully qualifiedvalue. 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.
