new draft, list of bugs to be filed

I have checked in an intermediate draft of the proposal and Richard has made
it available at http://www.w3.org/International/docs/html-bidi-requirements/
.

This draft is only meant to be suitable as a reference for the HTML5 bugs,
which I am about to start filing. I still have not updated a number of
sections of this draft, mostly ones without HTML implications (e.g. limited
to CSS), and have not made any of the stylistic changes that have been
recommended over the past year. I intend to do that after the HTML5 deadline
rush.

Section 2.2 (Support auto-direction) is not in its final state either. It
still has first-strong defined as returning LTR for numbers, which was
challenged today, and does not include autodirmethod=plaintext. There are
two reasons for the latter: the open issues in the plaintext spec, and lack
of time. I will be happy to put it in if and when we get it ironed out.

Here are the bugs that I see being filed on the basis of each section. ***
Important ***: please make sure that I have addressed (HTML vs CSS vs
Ecmascript) things correctly.

2.1:
- (HTML) ubi=ubi|""|off attribute. Asking WG to decide whether ubi value
should be "on" instead.

2.2 (update not complete):
- (HTML) dir=auto value, autodirmethod=first-strong|any-rtl|plaintext. The
last value may or may not make it in, depending on how ready it is.

2.3:
- (HTML) submitdir attribute (pure boolean)

2.4:
- (CSS) rtlflip keyword in background-image, list-style-image etc. Asking WG
to decide whether instead of rtlflip, ltr and rtl keywords.

3.1:
- (HTML) bidibreak=soft|hard attribute.

3.2:
- (HTML) LINE SEPARATOR (U+2028) and PARAGRAPH SEPARATOR (U+2029) in <textarea>
and in elements with white-space:pre|pre-line|pre-wrap should break lines
- (HTML) line breaks and PARAGRAPH SEPARATOR (U+2029) in <textarea> and in
elements with white-space:pre|pre-line|pre-wrap should act as UBA paragraph
breaks
- (Ecmascript?) line breaks and LINE SEPARATOR (U+2028) and PARAGRAPH
SEPARATOR (U+2029) in dialog text.

3.3:
- (HTML) block-display elements should act as UBA paragraph breaks
- (HTML) block element with display-inline to have ubi=ubi by default
instead of embedding

3.4 (not yet updated):
- (Ecmascript?) script dialog text direction
- (Ecmascript?) Unicode spec re Default Ignorable Code Points applies to
directional formatting characters in dialog text
- (Ecmascript) support optional direction parameter in alert(), confirm(),
and prompt()

3.5 (not yet updated):
- (HTML) <title> supports and inherits dir attribute
- (HTML) Unicode spec re Default Ignorable Code Points applies
to directional formatting characters in <title>

to directional formatting characters in title attribute

3.7:
- (HTML) <option> supports dir attribute, even after it has been selected.
- (HTML) <option> supports align attribute, even after it has been selected.

3.8
- (HTML) setting <input> and <textdir> direction through browser UI should
set the dir attribute and trigger oninput event
- (HTML) on an OS that has a widespread convention for setting direction, user
agent should support it

remembered too
