<xsd:element name="nameCRS" type="witsml:wellKnownNameStruct" minOccurs="0" maxOccurs="1">
<xsd:annotation>
<xsd:documentation>The name of the coordinate reference system in a particular naming system.
An optional short name (code) can also be specified. Specifying a well known system is highly desired.
An example would be to specify a name of 'WGS 84 / UTM zone 10N' with a code of '32610' in
the 'EPSG' naming system. Note that specifying a name in the EPSG naming system is asserting
that the parameters in the EPSG database are appropriate for this CRS. This is
also true for any other naming system. If in doubt, contact your local geodesist.</xsd:documentation>
