A design for a sampling feature that has no specialization of its own, such as atransect, a planar sampling feature or a volumetric sampling feature, typically onewhose conformance is judged mainly by location.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
