The following comments apply to article " Creating HTML Pages in Arabic, Hebrew and Other Right-to-left Scripts" (http://www.w3.org/International/tutorials/new-bidi-xhtml/Overview.en.php).
1) In "While it is important to note, that the HTML5 specification is still not completely stable", the comma after "note" is not needed.
2) In "within the general right-to-left visual flow of the text in general" there is one general too many (like in some armies).
3) We find: "What you need to know about the bidi algorithm and inline markup describes how language metadata differs from the actual language of the text, and discusses Content-Language as used in HTTP headers and meta elements."
The referred article does not mention any of metadata, Content-Language or HTTP.
