| ? | OPTIONAL, but MUST NOT occur more than once |

Notes
- If latitude is present, so MUST be longitude, and vice versa.
- The secondary classes can be omitted, the two values MUST be separated by a semicolon and latitude MUST be first. This is used with the ABBR design pattern and the title attribute:
<abbr class="geo" title="37.386013;-122.082932">Human Readable Text</abbr> - The same number of decimal places SHOULD be used in each value.
- Coordinates use the datum of WGS84.
- Sources for latitude/ longitude coordinates
