The geotechnical unit this relation applies to. Required, and perlayer. It references the diggs:GeoUnitObservation directly, theper-unit object in the ground model, not the enclosingdiggs:GeoUnitSystem, whose anchoring choice states what the modeldescribes rather than which unit this relation applies to.
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.

k_tau (shaft) or k_q (tip): the initial slope of the load-transfercurve, the mobilization stiffness at small displacement, before thefirst break of the curve.
The unit of measure for body force or unit weight.

q_s (shaft) or q_p (tip): the limiting unit resistance the curveplateaus to at large displacement. See the sign-convention cautionon diggs:LoadTransferRelation for the negative skin friction limit.
The unit of measure for pressure, stress, or elastic modulus.

The discretized (displacement, stress) series behind initialModulusand limitValue, where the full curve shape matters and not only itsinitial slope and plateau. It reuses diggs:ResultsPropertyType,whose diggs:ResultSet holds parameters and a columnar dataValuesarray: declare a displacement diggs:Property and a stressdiggs:Property under parameters, and the paired series underdataValues. It carries no spatial domain, because the domain of at-z or q-z curve is displacement, not geometry.

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.
