DALI says how to do file uploads, and I submit that that's the way to
upload multiple complex objects if that's what we want.

Again: Allowing lists of things rather than the things itself is a
*major* change of a protocol (i.e., think of the complexities of IP
multicast).  Please don't ad-hoc syntax with the goal of hiding this.

Plus, uploads aren't that awfully complex to implement, so anything
smart enough to be able to handle lists of geometries should by ok
with doing uploads and parsing the uploaded VOTables, too.

Cheers,
