RE: RE: SC 2.4.6 wording

That's fine, but we want to preserve some sense of logic even when presentation order doesn't affect its meaning.

So how about:

1.3.3 Meaningful Sequence: When content is navigated sequentially, ensure the navigation is meaningful by:
 o visiting every element that can receive focus (hereinafter refered to as a navigable element), and not revisiting any navigable element while there is an unvisited navigable element.

 o For navigable elements within a section of content where the order of presentation affects its meaning (hereinafter refered to as a block), navigate to the next navigable element in the inline progression direction (allowing for wrap) of the block.

 o For navigable elements outside the block, navigate to the first navigable element of the inline progression order in some other block (either the nearest block in the block progression direction, or the inline progression direction, at the authors choice).

 o Only navigate outside a block from the last navigable element in the inline progression order within the block. Elements not in a text run count as a complete block.

1.3.3's "the sequence in which content is presented affects its meaning" was an attempt to capture "continuous narrative text" more generally.

Separating the case where the tab order needs to follow the content from the places where there are options seems promising.

When we consider navigation between diconnected units of narrative text, there is more latitude; but some sense of locality is generally preferred.
