I don't recall what version.  It's also possible I'm remembering  
wrong and it's just something they mentioned possibly doing, or in  
development versions, or something.  I thought the notion did come  
from MS though.

But in any case, as the RFC allows for it, and it would be practical  
under 4120 for the next several decades (32-bit seconds => 136 years,  
unsigned means 1970-2106), I don't think the schema should prohibit  
it.  (And by 2106 I expect we'll have revised the data format again.)
