Hi,
Yes, indirectly I am looking for some solutions.
When we use css3 "border-radius" , W3C indicates "Parse Error Empty String" error. I dont find any solution to this issue. So I checked big websites like wordpress.org, cssmania.org, they have the same issue when validating their sites.
It is a prestigious issue for these big websites, so they might find a solution, or otherwise they might intimate this issue to W3C, because this is new , even most websites might not know this issues associated with their websites, becoz W3C changes their mind without intimating the community and without any reasons.
Giants like wordpress's words are audible to W3C. I am pretty sure there is no reason for this error "Parse Error Empty String" for using border-radius.
So I am making you all to have an awareness about this and you might check your websites and there might be some solutions or at least W3C should realize their mistakes.
