In order to resolve long standing bugs in the HTML5 spec, W3C I18N WG came up with Use Cases & Exploratory Approaches for Ruby Markup[1] note. After a discussion between I18N WG and HTML WG at TPAC, Robin @ HTML WG came up with HTML Ruby Markup Extensions spec[2], which was now merged into HTML5 CR Feb 2014[3].

Summary of changes are:
1. Properties of ruby and its related elements (rp, rt) are revised. This includes 8.1.2.4 Optional tags (a.k.a., tag omission rules)[4] for these tags.
2. Two elements are added (rb, rtc)

My group is working with Robin to add supporting tests to html5lib-tests[5], and we expect to finish it soon. Robin also prepared a pull request for html5lib[6], which indicates that the required changes in the parser is quite minimal.

I'd like to start working on this, along with importing the tests into webkit once it's done.
