-<xsd:annotation>
 <xsd:documentation>An empty string is the default representation of a null value for a curve (i.e. when the null value representation is not explicitly defined). If a null value is defined in the logCurveInfo, it overrides any null value specified at the logHeader level. An empty string is always a valid null value representation in the comma delimited list. An empty string is not a valid null value representation within a space delimited array. Specifying a null value also makes it easier to transform data back to a legacy format without having to scan the data to insure that the null pattern does not exist in the data. </xsd:documentation>
