The sampling feature a diggs:RelativeLocation's position is stated relative to, forexample the borehole a depth is measured down. Use in place ofdiggs:relativeToSampleRef where the reference point is a sampling feature ratherthan a sample. 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.
