Thanks for the clear post Ben.

This is very much the same issue that I've mentioned a few times WRT 
consuming hatom documents.... the added 'bonus' if you will with hatom 
is that you're typical usage will be to return to that document (or 
document fragment) repeatedly over time so its more important to handle 
some error conditions or other document changes over time.

I do think that 'root element must have id' goes a long way to solving 
the problem on the hatom side, but I don't know if that alone gets us 
all the way there.

And that says nothing about the questions of how a typical user might 
be able to identify the specific hcard/hevent/hatom/xoxo fragment to 
pass to another application if there was an ID requirement in place. In 
the above scenario you'd still have to have a way of learning that 
#event-002 is *the* event you want to spread around -- other then 
knowing because you're the author or you viewed source.
