Comment (including rationale for proposed change):

Seems similar to H1. What is the difference between using DIR attribute on inline and block elements?

Proposed Change:

Roll H1 and H56 into one technique or describe differences between use of DIR attribute on inline vs. block elements.

WG Notes: [TEAMB] Overcome by events: see LC-1383 Discussed in the 27 July 2006 telecon: accepted by unanimous consent http://www.w3.org/WAI/GL/2006/07/27-wai-wcag-minutes.html {partial accept}

Resolution: Based on comments from the internationalization working group, we have determined that text direction is only an accessibility issue when mixing text directions is done in a way that affects the sequencing of the text. So we have removed technique H1.
