If latitude is present, so MUST be longitude, and vice versa.
If the secondary classes are omitted, the two values MUST be separated by a semicolon and latitude MUST be first:<span class=geo">37.386013;-122.082932</span>
The same number of decimal places SHOULD be used in each value.
Coordinates use the datum of WGS84.
