A reference to a program basis object: the evidence, ground model, requirement setor other input a design or specification was prepared from. Distinct frombasedOnRef, which cites a more general object of the same kind that this onespecializes, and from programSpecificationRef, which cites a constraint the designmust satisfy.

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.
