Wrote up a simple XML document describing an app.

This is just a sample, got some issues left (the "name" property -> not
conformant with other object properties, etc) but well.

I did not write an XSD schema or some XSLT things, that's for later when
the final schema is made.

Please review and let me know what you think :-)
