<ul>
<li ism:ownerProducer="USA" ism:classification="U">1. Latitude shall be in decimal degrees in the range -90? less than or equal to latitude greater than or equal to +90?.</li>
<li ism:ownerProducer="USA" ism:classification="U">2. North latitudes shall be positive, south latitudes shall be negative.</li>
<li ism:ownerProducer="USA" ism:classification="U">3. Longitude shall be in decimal degrees in the range -180? less than or equal to longitude greater than or equal to +180?; note that there are two equally acceptable values of longitude for the meridian opposite the prime meridian.</li>
<li ism:ownerProducer="USA" ism:classification="U">4. East longitudes shall be positive, west longitudes shall be negative.</li>
<li ism:ownerProducer="USA" ism:classification="U">5. Only the element gml:pos shall be used to encode a geographic point location as either: a. two decimal values in the order of latitude then longitude (no commas) when WGS84E_2D, or b. three decimal values in the order latitude, longitude and finally height above ellipsoid (no commas) when using the WGS84E_3D CRS.</li>
<li ism:ownerProducer="USA" ism:classification="U">6. The outside edge of a linearRing is defined by four or more coordinate tuples, in counter- clockwise order, with linear interpolation between them; the first and last coordinates must be identical.</li>
</ul>
</li>
<li ism:ownerProducer="USA" ism:classification="U">Developer's Note: The srsName attribute is required on the Polygon element. The Polygon/@srsName is the identifier for the CRS which is controlling for the child gml:pos elements. It is important to note that the srsName attribute may also appear on the gml:pos elements, however given the current allowable CRSs above there is no need to repeat the information on the gml:pos elements thus the srsName attribute is optional and not required. If the srsName does appear on the gml:pos elements then it must be the same as the value of the srsName attribute on the Polygon element.</li>
