[CSSWG][css-writing-modes] Does not mention "auto" for the "direction" property

https://drafts.csswg.org/css-writing-modes/#direction

"2.1. Specifying Directionality: the direction property" section
only mentions "ltr" and "rtl" as the permissible values for the
"direction" property.

This is not aligned with HTML5, which also tolerates "auto"
(for the "dir" attribute - 
https://www.w3.org/TR/html5/dom.html#the-dir-attribute).

Is there any rationale for that?
