[OSGeo-Standards] Simple Text Format For Transfer of Simple Spatial Features (Killing the GML 3 Beast)

Yet another format is never a great idea :-) If you really want another 
format why not punt H2 databases around? It is what the SQLLite file 
format crazy in the C++ world is all about ... think even FDO does 
something like that?

You are welcome to look at the property file format we use as an example 
in GeoTools.

This is the way to go;
- you will find that the OGC has a SimpleFeature profile of GML3 that 
can be put to good use.
- ESRI also has something insane to the same effect

Not sure you will every eliminate the need for an external schema - but 
why not put it inline at the top of the document? Consider it a "header" 
for the rest of the file ... that is how WSDL and MS does it.

Cheers,
Jody
