1) NEW Introduced new anyUoM enumeration:

	<xsd:simpleType name="anyUom">
		<xsd:annotation>
			<xsd:documentation>areaUom is not specified elsewhere, so not included here.</xsd:documentation>
		</xsd:annotation>
		
		Merged in all UoM enum values from : witsml:pressureUom witsml:volumeUom 
		witsml:thermodynamicTemperatureUom witsml:lengthUom witsml:densityUom witsml:lengthPerLengthUom
		 witsml:timeUom
		 
	</xsd:simpleType>
	
and changed generalQualifiedMeasure to use it rather than <xsd:attribute name="uom" type="witsml:uomString" use="required">

<xsd:complexType name="generalQualifiedMeasure">
		...
				<xsd:attribute name="uom" type="witsml:anyUom" use="required">
					<xsd:annotation>
						<xsd:documentation>The unit of measure for the value. This value must conform to the values allowed by the measure class. The scheme has been updated to make this the union of all the UOM enumerations.</xsd:documentation>
					</xsd:annotation>
				</xsd:attribute>
	
	...
	</xsd:complexType>
