Notes

  • The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
  • Coordinates MUST use the datum of WGS84.
  • If latitude is present, so MUST be longitude, and vice versa.
  • Coordinates MAY be combined a single <abbr> element; then the latitude and longitude MUST be separated by a semicolon in the title attribute and latitude MUST be first:
<abbr class="geo" title="37.386013;-122.082932">home</abbr>
