RE: Add Dragging SC to WCAG 2.2 draft

Apologies, I missed this thread before I sent the other idea around.

I’m happy with Detlev’s approach, which comes out like this when formatted for our definitions:
----------------
<p>an operation where the pointer engages with a <a>target</a> on the down event and the target (or an element representing its position until release) follows the pointer until the up event without requiring movement in a specific direction at the start of the movement</p>
<p class="note">The target could be, for example, a list item, a text element, or an image.</p>
----------------

With our definition of target (which is a region of the screen that accepts pointer input), there isn’t much difference.

The last bit about movement in a specific direction is to separate it from path based gestures, 2nd paragraph here:
https://www.w3.org/WAI/WCAG21/Understanding/pointer-gestures.html

“A path-based gesture involves an interaction where not just the endpoints matter. If going through an intermediate point (usually near the start of the gesture) also affects its meaning then it is a path-based gesture."

Now I reminded myself of that, maybe it would be better to match the (reverse of) the definition?

If we remove target and adjust that, it would be:
<p>an operation where the pointer engages with an element on the down event and the element (or a representation of its position) follows the pointer until the up event, without requiring movement through an intermediate point</p>
<p class="note">The element could be, for example, a list item, a text element, or an image.</p>

How’s that?
