I have posted an updated version of the Atom Bidi Draft. The only significant difference is a notice about direction guess algorithms.
http://www.ietf.org/internet-drafts/draft-snell-atompub-bidi-03.txt I have implemented support for this specification in Abdera and in IBM's updated internal blogging environment. The specification adds a new attribute "dir" to the set of common attribute attributes within the Atom namespace. The dir attribute specifies the default directionality of language-sensitive text within an Atom document. example, <entry xmlns="http://www.w3.org/2005/Atom" dir="rtl"> ... </entry> At this point, I intend to request a formal last call on the document and recommend it for publication as an experimental or informational draft. Feedback is requested. - James
