Are "control" and "user interface component" interchangeable?

[innoticFR]

I am seeking clarification on the exact scope of the terms "control" and "user interface component" within the WCAG 2.2 definitions.

In 4.1.2, the link to the "user interface component" definition states:

"A part of the content that is perceived by users as a single control for a distinct function."

And in 1.1.1 (Non-text Content) says:

"Controls, Input: If non-text content is a control or accepts user input..."

Without this definition, my usual interpretation would have been that a UI component includes anything with a non-presentational role (even if not interactive), whereas a control would imply something actionable (buttons, links, form fields, etc.). But since the definition of 'UI component' itself uses the word 'control', the terminology in 1.1.1 would feel ambiguous if control had a broader sense.

Could you confirm if my understanding aligns with the W3C intent : is a UI component equivalent to a widget as defined in ARIA? And so is a "control"?

See also 2.4.10 Section Headings

This success criterion covers sections within writing, not user interface components

Here the use of user interface components for receiving "headings" is quite ambiguous with the definition...

I close this discussion as this is already addressed in #4252 and #4234
