-<xsd:sequence>
-<xsd:element name="sourceName" type="witsml:nameString" minOccurs="0" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>An identifier to indicate the data originator. This identifies the server that originally created the object and thus most of the uids in the object (but not necessarily the uids of the parents). This is typically a url. </xsd:documentation>
 </xsd:annotation>
 </xsd:element>
-<xsd:element name="dTimCreation" type="witsml:timestamp" minOccurs="0" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>When the data was created at the persistent data store. In a query template, a specified value will be interpreted by the server as a request for dTimCreation values that are greater-than the specified value. </xsd:documentation>

 </xsd:annotation>
 </xsd:element>
-<xsd:element name="dTimLastChange" type="witsml:timestamp" minOccurs="0" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>Last change of any element of the data at the persistent data store. The change time is not updated for a growing object while it is growing. In a query template, a specified value will be interpreted by the server as a request for dTimLastChange values that are greater-than the specified value. The dTimLastChange value may be changed by a client (user). </xsd:documentation>

-<xsd:element name="itemState" type="witsml:ItemState" minOccurs="0" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>The item state for the data object. </xsd:documentation>
 </xsd:annotation>
 </xsd:element>
-<xsd:element name="serviceCategory" type="witsml:kindString" minOccurs="0" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>The category of the service related to the creation of the object. For example, "mud log service", "cement service", "LWD service", "rig service", "drilling service". REALTIME STORE UNIQUE KEY: When accessed via the Store Interface, for each instance of realtime, the combination of "uidWell", "uidWellbore", "idSub" and commonData's "serviceCategory" must be unique. That is, the Store Interface will only retain one realtime for a particular wellbore, subscription and service with the REALTIME STORE UNIQUE KEY being the object selector.</xsd:documentation>

 <xsd:documentation>Comments and remarks. </xsd:documentation>
 </xsd:annotation>
 </xsd:element>
-<xsd:element name="acquisitionTimeZone" type="witsml:timestampedTimeZone" minOccurs="0" maxOccurs="unbounded">
-<xsd:annotation>
 <xsd:documentation>The local time zone of the original acquisition date-time values. It is the deviation in hours and minutes from UTC. The first occurrence should be the actual local time zone at the start of acquisition and may represent a seasonally adjusted value such as daylight savings. The dTim attribute must be populated in the second and subsequent occurrences if the local time zone changes during acquisition. This knowledge is required because the original time zone in a dateTime value may be lost when software converts to a different time zone.</xsd:documentation>
