-<xsd:annotation>
 <xsd:documentation>Whether or not the wellLog is growing. True ("true" or "1") indicates the that the wellLog is still growing in size (that is, logData values are still being added). For example, it may be connected to a realtime stream. False ("false" or "0") indicates that the wellLog is closed (that is, no further logData values will be added). Not given indicates that the status of the wellLog is not known. This value is only relevant within the context of a server.</xsd:documentation>

-<xsd:element name="nullValue" type="witsml:encodedValueString" minOccurs="0" maxOccurs="1">
-<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 representation is defined for a log, this becomes the default for all curves in that log (but can be overridden at the block and curve 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 or base64 encoded 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>
