A description of the geometry of vectors or planar surfaces encountered at asampling feature, such as bedding, joints or cross-beds, characterizing regions ofgeneralized geometry. Individual measurements of the planes of boundaries or faultsare recorded in diggs:DiscontinuityObservation or diggs:Lithology instead.
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.
A legacy attribute for AGS trial pit sampling features, whereobservations of different strata can occur at the same depth in a pit: areference letter or number whose sole purpose is to link the stratum onthe face sketch of the trial pit to the observation.
