The ValidityEnumType enumerates values that describe the validity of a coordinate or set of coordinates. A coordinate can be present and correct in a report (REPORTED). A coordinate may be missing from a report but will have a value determined by one of several means: it may be an arbitrary value (DUMMY), it may be an arbitrary value that is meaningless such as the third coordinate in two-dimensional measurement (MOOT), it may be derived (calculated) from other values (DERIVED), or it may be set to a value (SET) typically the nominal value.
