Thanks Erich,
Just to check it was captured, I think it would help to add a short paragraph on what the exception for 2D covers.
Jim, I think you’re editing this one, how about adding the following text above the last paragraph in Intent (that starts “User agents for…”.
Certain content cannot be reflowed without losing meaning so there is an exception for that type of content. For example, graphics and video are by their nature two dimensional. Cutting up an image and stacking the blocks would render the content unusable so that is out of scope.
Complex data tables have a two-dimensional relationship between the headings and data cells. As that relationship is essential to convey the content, this success criteria does not apply to data tables. Lastly, interfaces which provide toolbars to edit content need to show both the content, and the toolbar in the viewport. Given enough buttons, that toolbar may need to scroll in the direction of text (e.g. horizontally in a vertically scrolling page).
And, whilst outlining those exceptions, we should probably add advisory techniques for:
* CSS, Fitting images to the viewport;
* CSS, Reflowing simple data tables.
* CSS, Fitting data cells within the width of the viewport.
Cheers,

Hi folks,
I was asked to review the Understanding Doc for Reflow<https://rawgit.com/w3c/wcag21/reflow/understanding/21/reflow.html>.
Overall I find it logical and clear, and believe that it will help developers.
Thanks,
