2.1.1 [W3C-WEBNOT] Section 4.1 Direction

V0001: The "auto" value of the dir attribute is not supported

The specification states:

 2.3. Direction
 ...
 User agents are expected to honor the Unicode semantics of the text of a notification’s 
 title, body, and the title of each of its actions. Each is expected to be treated as an 
 independent set of one or more bidirectional algorithm paragraphs when displayed, as 
 defined by the bidirectional algorithm’s rules P1, P2, and P3, including, for instance, 
 supporting the paragraph-breaking behavior of U+000A LINE FEED (LF) characters. For each 
 paragraph of the title, body and the title of each of the actions, the notification’s 
 direction provides the higher-level override of rules P2 and P3 if it has a value other 
 than "auto".
