I18N-ISSUE-34: bdo element doesn't leave rendering up to presentation layer  [HTML5]

http://www.w3.org/International/track/issues/34

Raised by: Richard Ishida
On product: HTML5

4.6.21 The bdo element
http://dev.w3.org/html5/spec/text-level-semantics.html#the-bdo-element

WG Approved: Yes


"If the element has the dir attribute set to the exact value ltr, then for the purposes of the bidi algorithm, the user agent must act as if there was a U+202D LEFT-TO-RIGHT OVERRIDE character at the start of the element, and a U+202C POP DIRECTIONAL FORMATTING at the end of the element."

"If the element has the dir attribute set to the exact value rtl, then for the purposes of the bidi algorithm, the user agent must act as if there was a U+202E RIGHT-TO-LEFT OVERRIDE character at the start of the element, and a U+202C POP DIRECTIONAL FORMATTING at the end of the element."

The section about the <bdo> element does *not* leave the expected behavior completely up to the presentation layer - which is confusing. Content authors need to know if they should use CSS, if CSS would override the specified behavior etc.
