I understand that it's not good to implement features that won't be used 
by anyone in the end. Nevertheless I am worried that this could lead to 
a chicken or the egg dilemma, i.e. HTML waits for CSS to implement 
styling (year-only) dates and CSS waits for HTML implementing 
year-only-dates before making them stylable?

I also wonder whether this needs to be handled by CSS? I think browsers 
could show a tooltip just like Opera shows a tooltip displaying the URL 
for links. Some browsers also use a status bar at the bottom to show 
this otherwise hidden data. It would be great if browser developers 
could give their opinion on this!
