Type of test conducted from the following controlledlist: 1) constant head; 2) falling head, constant tailwaterelevation; 3) falling head, rising tailwater elevation; 4) constantrate of flow; 5) constant volume-constant head (by mercury); 6)constant volume-falling head (by mercury), rising tailwaterelevation;
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.
