Hello,

I believe following HTML is valid (as W3C HTML 5.0), but the validator says 
"Element rb not allowed as child of element ruby in this context. (Suppressing 
further errors from this subtree.)".


<!DOCTYPE html>
<html>
<head>
<title>The rb element testing</title>
</head>
<body>
<p>
<ruby><rb>base<rt>annotation</ruby>



Best Regards,
NAKAMURA, momdo
