Extended GPX Schema

I'm putting together an extended schema for GPX to allow me to put runway
and communications data and other airport and navaid data into GPX. Are
there any other people out there writing applications that need aviation
data or that provide aviation data that would be interested in cooperating
on the definition of the schema?

You can find a preliminary schema at http://navaid.com/GPX/NAVAID/0/2

me as the most damaging to the ideal that all Americans are created equal
and owe equal allegiance to their country." - Colin Powell (pre-sell out)
