Clarifying it further. My example is from publishing perspective i.e. mostly read only documents that are published.
If we are looking at this from purely word processor perspective, then I wonder if this is a publishing related issue?

I think that I am able to get the expected functionality, at the same time I am still confused with placing page numbers in footers or headers.
Explaining it in step wise manner
- The text will reflow but the headers and footers are expected to remain constant.
- For example, if the document has footers after approximately 20 lines and the user zooms to double size, then there will be one footer after each 7 or 8 lines.
- This means that page breaks will also flow down.
Now, how can one mark persistent page number inside header or footer. In such a case the page number in footer will become reading system responsibility which will change dynamically instead of being responsibility of content.
If we want to have static page numbers in header or footers then it should be a fixed layout,
or the header / footer should also reflow when user zooms the document.
With regards

Perhaps the screen readers should offer a means of querying the header/footer information. However, that’s outside the scope of ARIA and a matter for each implementation. This would be especially useful in a word processor, as the user needs to be able to read and edit it. Another option would be a simple “go to header/footer” navigation command in the application itself.
I’m not sure that I fully understand George’s question about export to EPUB. When the text is reflowed, the pagination may change, but the header/footer text often wouldn’t. A good example would be printing to different page sizes or font sizes. If the text still fits, then presumably it should simply be printed wherever the new page breaks lie after styles are applied to the document. It’s very much the same as what happens if you make changes to a document in a word processor. If there are no explicit page breaks in the markup, then the page header/footer should be able to be applied to an entire div/section of the document:
<section role=”doc-chapter”>
<!—Applies to all pages in this section -->
<div role=”doc-pageheader”>[…]</div>
[…]
</section>
I’m not in a position to answer Aaron’s earlier question about the schedule for specifying new ARIA features for these use cases. I think that’s a question for the Chairs, or for a group meeting.

Hi,
A few items here:
I totally agree that while creating content as in GoogleDocs, it is perfectly fine to have running footers and Headers. Even better if I, using my screen reader, do not need to encounter them.
The export to EPUB would not put this in the reflowed content, right?
Page numbers are one of those things we have called “skippable” structures. In an audio book, you may want to go to page 34 and hear that this is page 34, but in continuous reading, you want to skip (filter is your term) over it. However, It is always good to stop and find out where you are.
Seems that this agreement.

George

Subject: Re: Running headers/footers / new version of DPUB-ARIA?
George -- we're in agreement. This will help paginated content just seem like one continuous document when you're reading. Basically, we're trying to make it so that you don't see this stuff when you're word processing unless you want to. By having the word processor (like Google Docs) mark these up, the AT can decide to filter those things out, which they can't do right now. See Glen Gordon's comments in the bug. This will allow them to have similar functionality for this in Google Docs as they do on MS word. Where are we not aligned here?
Avneesh -- DPUB is very close to being able to help us have an awesome experience in Google Docs. Makes sense as a use case, right?
Jason -- can you give an example? I think we want 2 things from the page number -- to be able to report it when the user wants it, and to be able to filter it out when the user just wants to read continuously (similar to filtering out the page header).

I think that the confusion comes from the design. Most of the DPUB aria roles are from the perspective of a refloable document like HTML and EPUB 3. On the other hand the discussion in this thread looks more oriented towards somewhat like a fixed layout document.

Thanks, I didn't realize that's where the page number would currently go. I'm not sure it's ideal.
<span id="pg04" role="doc-pagebreak" title="4"/>A page break line would likely show up as a horizontal line. Under the horizontal line is a header, then adjacent to that comes the page number. How would that be done in markup?
We don't want 2 page breaks, and the page break and page number aren't in the same place.
<hr role="doc-pagebreak">
<div role="doc-pageheader">
My header <span role="doc-pagenumber">4</span>
</div>
Additionally, in the page break example, the page number usage is in the title attribute, which would not be visible text. Although it's not explained, t's not clear to me from the example or spec text that browsers/ATs could expect a page number inside a child text node.
IMO we should have a separate role for page numbers, or put them inside the header or footer objects, but putting them as part of the page break to me will cause a problem with the above example.

doc-pagebreak already exists in DPUB aria roles for locating the page marks. They can have a visible page number as well as invisible page number.

Thanks Leonard, don't we want to be able to differentiate the headers from the running headers? It's the repeated running headers that users want to skip over.
The headers that are part of the content seem different, like a <header> in HTML.

In PDF, we treat page numbers as a separate thing from the header/trailer (and yes, you can have the former inside the latter). We also have a “class” for bates numbers and a few other vertical-specific elements. We have found that it is important to be able to unique identify them.
Headers and Footers aren’t necessary tied to pages – you could have a section with a header or footer as well, so perhaps just `doc-header` and `doc-footer` (and `doc-pagenum`).

Sounds good.
- How about doc-pageheader and doc-pagefooter?
- Possible definition: repeated section of text that appears at the top/bottom of pages in a document, potentially containing a title, page number or other information
- Should the page number get its own role, e.g. doc-pagenum? Should it exist within the doc-pageheader/doc-page-footer?
- Should the new roles inherit from contentinfo?

If there’s already a mapping to accessibility APIs via PDF readers, then we could use it here too.
Screen readers could offer a command to query this information, if desired, just as there is for window titles.

FWIW: Headers & Footers can be properly identified in PDFs and exposed accordingly to AT (so that they aren’t read multiple times). In fact, PDF/UA (the PDF standard for Universal Accessibility) calls out their usage.

Hello,
This is just my opinion. Running headers and footers are very intrusive while reading. I encounter these many times in PDF documents. The same information is constantly repeated. Fortunately, I do not encounter this while reading EPUB. I can understand that it might be useful for the Reading System to provide “where am I?” information as one is reading, but including this over-and-over again in the content would be horrible.
I am reading using Assistive Technology (AT) and the TTS reads to me. I imagine this would also be painful if a person was using the read aloud function in Reading Systems.
I could see the same problem in an audio book. Nobody would want to hear those running heads and footers in the audio book.
My $.02

Hi all,
I'm wondering about the plans for doing DPUB-ARIA 2.0 as described under the deliverables:
https://www.w3.org/2017/04/publ-wg-charter/#deliverables
Thanks for what DPUB-ARIA provides so far. Google Docs is going to be using it to expose semantics for online word processing. We're collaborating with AT vendors and other developers of online word processors as well.
One gap is running headers and footers: https://github.com/w3c/dpub-aria/issues/10 -- hence the reason for my email and status check :)
Thanks for any info,
Aaron
