Hmm... Can't resist also ;-)

Yes, AFAIUnderstand VO, it has been conceived as a generic Table structure,
but at the same time as an 'unperfect' Fits improvement (streaming possibilities,
ols days limitations removal, like 8char keyword length... see VOTable
document intro). And because fits does not concern only table, VOTable too.
Both are generic structure/container, but the separation of metadata/data
is clearer in VOTable and this is a major advantage for VO interop IMHO.

Waiting the perfect tool and the messiah, or the miracle (Leonard Cohen 1992),
let's play with what exists meanwhile.
