ISSUE-117: Close definition of dir auto

Close definition of dir auto

Description: The xml:base attribute (XML only)

The dir 'auto' value has this note:

The heuristic used by this state is very crude (it just looks at the first character with a strong directionality, in a manner analogous to the Paragraph Level determination in the bidirectional algorithm). Authors are urged to only use this value as a last resort when the direction of the text is truly unknown and no better server-side heuristic can be applied.

Does HTML5 need to define auto so closely that no user-agent can provide a better algorithm? That seems counter-productive. Some room for innovation should be preserved.
