That's 3 months for a W3C Candidate Recommendation to become a proper Recommendation not 3 months until the vast majority of XML parsers support this. The normal time is at least a year between a Recommendation and wide availability of implementation compliance so on this basis, I think that the VOEvent community cannot live with extra effort required until at least 2007.
