Below is an example of the microformat-shiv parsing a h-geo. This microformat is used to describe geographic coordinates and is based on a property from the vCard standard. The HTML can be marked up so the numbers are visible or hidden to a human reader.
My favourite hill in the lakes is Pen-y-ghent. It raises to 694m.
The library supports both version 1 and 2 microfomat HTML mark-up patterns. You can check the compliance of the microformat-shiv to the h-geo standard by using the microformats test suite.
