UAAG2 proposed IERs for new reflow-related SCs

The SC wording was approved here http://lists.w3.org/Archives/Public/w3c-wai-ua/2014JanMar/0036.html

Now that 1.8.7 is removed, the numbering will probably be: 1.8.13, 1.8.14, 1.8.15.

1.8.X Multi-Column Text Reflow: The user can specify that recognized multi-column text blocks each be reflowed into a single column. (Level AA)

Intent of Success Criterion 1.8.X:
---
Keeping oriented within multi-column content can be challenging for some users, especially when content is zoomed. This is an especially acute issue for users who find it difficult or impossible to use the mouse to scroll and for users who find it difficult to reorient when the content changes. This does not require or prohibit the user agent from providing an option to turn off reflow.

Examples for Success Criterion 1.8.X:
---
- Frank has repetitive strain injuries and uses speech input. When Frank is using his mobile phone to read a web page, he will zoom in to read a article on a web site. He configures his mobile phone so that the text reflows to always display zoomed content to fit in one column.

- 1.8.Z Linearize Content



1.8.Y Ignore Absolute Layout Dimensions: The user can have the user agent override author-specified absolute layout dimensions. (Level AA)

Intent of Success Criterion 1.8.Y:
---
Content is not as easily usable if the user has to scroll back and forth horizontally. This is an especially acute issue for users who find it difficult or impossible to use the mouse to scroll and for users who find it difficult to reorient when the content changes. Since most user agents default to reflowing content within the horizontal dimensions of the top-level viewport, this success criteria gives users the option to check whether the default reflow might be sufficient for them.

Note: Some layouts, especially rich internet components such as spreadsheets, may become unusable if author-specified absolute layout dimensions are overridden. In this case, the user can turn those layout dimensions back on and try another strategy.

Examples for Success Criterion 1.8.Y:
---
- Maggie has cognitive issues that make it difficult for her to reorient when the computer screen changes. Finding and activating scrollbars, then finding the next words in the sentence requires extra effort and causes Maggie to lose her orientation, which degrades her reading flow and comprehension. When text is reflowed so it is in one column that doesn't require horizontal scrolling or vertical scrolling to get to another column, she can read and understand it.

- 1.8.X Multi-Column Text Reflow 
- 1.8.Z Linearize Content



1.8.Z Linearize Content: The user can have recognized content rendered as a single column, overriding author-specified formatting of columns, tables, and positioning. (Level AA)

Intent of Success Criterion 1.8.Z:
---
In some cases, author-specified layouts (e.g. such as layout tables, layouts that must be scrolled, etc.), can impede access, especially when content is zoomed. This is an especially acute issue for users who find it difficult or impossible to use the mouse to scroll and for users who find it difficult to reorient when the content changes.

Note: Some layouts may become unusable if author-specified layout is overridden. In this case, the user can turn linearization off and try another strategy.

Examples for Success Criterion 1.8.Z:
---
- Ansgard has low vision and physical disabilities that makes it difficult to use the mouse. He zooms text to read it. When using his PDF viewer, he makes use of the zoom and a single column reflow features to reflow the content into a single column that fits the window. This is especially useful for scientific papers and newsletters that are in that are multiple columns.
