In the values section of action, there are a values that move positions left and right, but no corresponding logical values start and end that take into account bidirectional text handling (and the corresponding mirroring of layout). While there is a need for absolute left/right positioning, there should be a way to do logical positioning based on layout.

I also notice that there are no up or down values. Is this an omission? (The corresponding logical directions, using CSS's terminology, would be block-start and block-end)

For some illustrations that show what the impact of bidi is on page layout, see this article.

Becky has added start/end, up/down, updated defintion of left/right to refer people to next/previous if the navigation is logical rather than physical. Please find changes in pull request #163. Thank you for your comments.

Changes complete in the latest draft.
