[ID] 7 [Location] 4.6.18 The ruby element [Subject] Please add support for rb [Owner] RI [WG] - [Ed. / Subs.] E [8] EditDelete [Comment] 
In all the web sites that we looked at that currently use ruby markup in the wild, over 90% of code uses the rb tag. The current HTML5 model for ruby simplifies the code generally, but making the rb element obsolete will make most existing ruby code non-conformant and make it more difficult to copy code that follows the Ruby Annotation model, from XML or other formats, into HTML5. Please allow optional use of the rb element as part of the HTML5 model.
