Content Element Detail (defined in this component only; 5/5)
ExternalURI
Type:
xs:anyURI, predefined, simple content
Note that ExternalURI points to the boundary file location.
XML Source (w/o annotations (1); see within schema source)
<xs:element name="ExternalURI" type="xs:anyURI"/>

GeographicTime
Type:
DateType, complex content
A time which corresponds to the identification of a geographic region described by a polygon. This may be a range if historical.
XML Source (w/o annotations (1); see within schema source)
<xs:element ref="GeographicTime"/>

Point
Type:
PointType, complex content
A geographic point defined by a latitude and longitude.
XML Source (w/o annotations (1); see within schema source)
<xs:element maxOccurs="unbounded" minOccurs="4" ref="Point"/>

PolygonLinkCode
Type:
xs:string, predefined, simple content
The PolygonLinkCode is the identifier of the specific polygon within the file. For example in an NHGIS file the LinkCodeForPolygon for Tract 101.01 in Hennepin County in Minnesota is 2700530010101.
XML Source (w/o annotations (1); see within schema source)
<xs:element minOccurs="0" name="PolygonLinkCode" type="xs:string"/>

ShapeFileFormat
Type:
xs:string, predefined, simple content
The format of the shape file existing at the location indicated by the sibling ExternalURI element.
XML Source (w/o annotations (1); see within schema source)
<xs:element minOccurs="0" name="ShapeFileFormat" type="xs:string"/>
