Beauty lies in the eyes of the beholder I guess.
I see DIV this, Class that, a bunch of angle
brackets, alternative forms. So much extra stuff
for so little gain, and, bonus!, incompatible with
prior formats.

As one simple but effective example, the
coordinates could be encoded in a conventional
URL. A few years ago, someone wrote an
interesting little web spider that harvested web
pages containing map-generating URLs referring to
popular mapping sites (Topozone, Tiger Map Server,
etc.). The author extracted the coordinates from
the URLs and plotted them on some maps, showing a
number of interesting ways to visualize
statistical and other information about the data.
The code that detected and parsed the URLs was
quite simple, and could have been even simpler if
the author had chosen to handle only URLs
referring to a a single map generator, such as
Tiger.

Also, there have been numerous prior XML formats
for representing geospatial data, including
Garmin's format and several for GIS applications.
