You're welcome, James.

However, there are still some issues. What should Atom processors do when they encounter a "dir" attribute with invalid or unknown value? 

For example:

<entry dir="rtl">
  <title dir="invalid">...</title>
  ...
</entry>

Should the directionality of atom:title continue to be right-to-left? In other words, should the dir="invalid" be ignored and keep the directionality inheritance? Or, is the recovery action left to be implementation-dependent?

In the example, the directionality of atom:entry is "rtl", there is no reason for the author to reset the directionality with an empty string. He should either change the directionality to "ltr" in atom:content or keep "rtl" by not using any "dir" attribute in atom:content.

However, for compatibility with existing Atom documents that rely on direction guessing, user agents MAY perform direction guessing in Atom documents that do not contain a "dir" attribute but they MUST NOT do so when Atom documents contain a "dir" attribute.
