Mime type for annotated data

[Laurent Michel]

Mark,

Honestly, I haven't considered using the VOTable mime type, but that might work.

My motivation for suggesting this is twofold:
1- An annotated VOTable is a VOTable that contains an XML block that obeys its own schema. In other words, it is something different from a regular VOTable. So having a specific mime type makes sense.
2- More pragmatically, having a specific mime type allows clients to request annotated data via the &FORMAT TAP parameter as they could for any other format (JSON...).
