The W3C has released XHTML 1.1 as a W3C Recommendation, as well as a new XHTML module, Ruby Annotation.
There appear to be very few changes between the Proposed Recommendation of XHTML 1.1 and the final version. XHTML 1.1 is much like XHTML 1.0 Strict, except for a few changes, including the addition of the Ruby module.
The Ruby module defines:
"short runs of text alongside the base text, typically used in East Asian documents to indicate pronunciation or to provide a short annotation"
The Ruby Recommendation includes a change list, most notably the addition of conformance rules.
Ruby annotation has nothing directly to do with the Ruby scripting language.
