Responsive design generally has the effect of allowing for 200 percent zoom or more on text -- however I'm not sure that is a given. On the desktop at least zooming in the browser changes the width of the window and increases the scale. In theory a developer could use fixed font sizes at different break points or do something that caused the text to change but not actually reach 200% at 200 percent zoom. Although web browser scaling above 200 might be reached 200% through scroll bars.

As an aside on a mobile browser where you can pinch zoom (when not blocked by the site or forced by the browser ) the ability to resize text alone is restricted to certain browsers or sites that use the system fonts that support the text size settings on the platform. So g142 allows mobile sites to meet the success criteria on small screens where text resize alone migh be more difficult.

I totally support text resize without zoom and believe it is a user requirement and need.
