The point was that VOEvent shouldn't be transfering data but reporting the existence of such data. Thus, the data format is - formally - irrelevant.

As little as the VOEventers generally like STC, we've been there, done that: STAP needs STC-compliance to be fully general (if one reports a solar flare that might be connected with a later ionospheric radio squak, what's the meaning of "UT"?) and STC needs (again) to be pushed to support really simple STAP-like queries (via standard STC time environments, just as we pushed standard sky- coordinate environments) to minimize the STC-gobblety-gook.
