>
> The span element is specified here:
> http://dev.w3.org/2006/waf/widgets/#the-span-element
>
> The processing step that defers to the yet to be written [WIDGET-BIDI]
> specification is defined here:
> http://dev.w3.org/2006/waf/widgets/#rule-for-getting-text-content
>
> The specification makes it mandatory that a user agent implement the
> WIDGET-BIDI spec:
>
> "A user agent is an implementation of this specification that also
> supports [XML], [XMLNS], [UTF-8], [DOM3CORE], [SNIFF], [WIDGETS-BIDI],
> and [ZIP]..."

> We would appreciate your review and any assistance you can provide.
> In particular, we would appreciate your guidance into what would go
> into the Widgets Bidi specification (i.e., how processing is done for
> dir and span). At the moment, we only have the following text for such
> a specification (based on HTML5's bdo element):
>
> [[
> If an 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 requirements on handling the span element for the bidi algorithm
> may be implemented indirectly through the style layer.
