Hi James and Sailesh


I've tried to capture these ideas in a way that will help web designers do
the right thing and not get confused with edge cases. I added to end of
description :


"Using Landmarks should not be considered a replacement for other native
semantics such as HTML headings, lists and other structural markup.
Landmarks are interpretable by WAI-ARIA-aware assistive technologies and are
not exposed by browsers directly to users."


I tried the capture the essence of Marco's blog, Jason, and Steve F. and
others advice about prudence using the application role by adding the


"(note: The role of application should only be used with caution because it
gives a signal to screen readers to turn off normal web navigation controls.
Simple widgets should generally not be given the application role, nor
should an entire web page be given the application role, unless it is not to
be used at all like a web page, and not without much user testing with
assistive technology.)"


And I addressed the conversation about one main element with the following:

"Generally, a page will have only one role=main."


I realize there are cases when the spec would allow more than one main
element, and I have been following the discussions on the blogs and twitter
about it, but I don't want to confuse average web masters with these
techniques documents, and  rather leave that open using the word "generally"
for others to investigate who may be hard core developers doing
sophisticated portals with multiple nested document nodes. Perhaps a
footnote would satisfy that crowd, or a link in the resources. But I'd
rather keep it out of the description section, because I don't think that
was its "main" purpose. Is that OK?

Please see inline starting with JN:

2. It is useful to mention that a page should have only one role=main.


JN: This is not strictly true. The spec states 

Within any  <http://www.w3.org/TR/wai-aria/roles#document> document or
<http://www.w3.org/TR/wai-aria/roles#application> application, the author
SHOULD mark no more than one
<http://www.w3.org/TR/wai-aria/terms#def_element> element with the main

Note: Because document and application elements can be nested in the DOM,
they may have multiple main elements as DOMdescendants, assuming each of
those is associated with different document nodes, either by a DOM nesting
(e.g., document withindocument) or by use of the
<http://www.w3.org/TR/wai-aria/states_and_properties#aria-owns> aria-owns


So - if the page has multiple documents (for example a portal type page
which can embed content from other sources), then multiple main landmarks
are possible.

Thanks, David. Also, is Using ARIA landmarks to
bypass blocks of content, and provide programmatic structure
obsolete, or something you will get to later? I
haven't looked closely, but it seemed very similar to
this technique.

I've completed the Landmark
technique edits and am ready to present for survey.
