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
