-<xsd:element name="badSetFlag" type="prodml:logicalBoolean" minOccurs="1" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>Set to 'true' when a measurement is included but is known to be bad (i.e. all the values are null). Use this flag in situations when you want to keep track of the fact that a measurement was generated/received however the measurement was bad.</xsd:documentation>

-<xsd:element name="emptySetFlag" type="prodml:logicalBoolean" minOccurs="1" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>Set to 'true' when the measurement set is empty (only the header is provided). Use this flag for situations when the instrument box attempts to get a reading but nothing is generated (fiber is disconnected, for example).</xsd:documentation>

-<xsd:annotation>
 <xsd:documentation>This supports user-defined "tags" (in the form of text strings) to be attached to the measurement. Example: to indicate other operations under way at the time (e.g., "start of injection").</xsd:documentation>
