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.
