ISSUE-36: New dir attribute value: auto, and a new attribute: autodirmethod

New dir attribute value: auto, and a new attribute: autodirmethod

State:

CLOSED

Product:

Description:

Make simple direction estimation functionality available in the browser by allowing the dir attribute to take on a new "auto" value indicating that the user agent is responsible for estimating the direction of the element's contents according to an algorithm specified by a new attribute, autodirmethod=first-strong|any-rtl.

This is a part of the proposals made by the "Additional Requirements for Bidi in HTML" W3C First Public Working Draft. For a full description of the use cases and the details of this proposal, please see http://www.w3.org/International/docs/html-bidi-requirements/#auto-direction.

In addition, also allow a third autodirmethod value, "plaintext", which would estimate the direction of each UBA paragraph in the element separately. This is intended primarily for the <textarea> and <pre> elements, where taking as input and displaying (mostly plain) text consisting of paragraphs with different directions is a fairly common need. The CSS3 spec already provides support for this feature via a new unicode-bidi value, "plaintext" (http://dev.w3.org/csswg/css3-text-layout/#unicode-bidi). However, some aspects of the feature still need to be worked out at this time.
