The relative density of a soil is the ratio, expressed as a percentage,of the difference between the maximum index void ratio and the field void ratio of acohesionless, free-draining soil; to the difference between its maximum and minimumindex void ratios.
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.
