Issue with List schema : What is Direction?

Question

List.Direction property

Gets or sets a value that specifies the reading order of the list.

It must conform to the following ABNF: Direction = “NONE” | “LTR” | “RTL”.

I would like to know the exact meaning of direction. Because this may help to solve this issue: Webpart cannot be seen on page after adding. Error in ULS. Feature (wsp) = Webpart+ListInstance

Answer 1

MSDN documentation says the following

Direction, Required Text. Specifies the direction of the reading order for the list. Possible values include RTL (right-to-left), LTR (left-to-right), or none.

Languags can be Right-To-Left, like arabic and Left-To-Right Languages like english. This can have an impact on things like sorting, filtering etc.
