The more I think about this checkpoint, the more I fear that it's extremely vague as written: "1. For graphical user agents, provide programmatic read access to visually rendered information." This is the first appearance of this checkpoint. It has not received the same level of scrutiny as other checkpoints in pursuit of minimal requirements. Rich's comment highlights that fact. I think the Working Group needs to spend some time identifying a minimal set of requirements for rendered information that must be available through an API. Input from people with experience using MSAA and other APIs is extremely important here. Thank you, _ Ian -- Ian Jacobs (ij@w3.org) http://www.w3.org/People/Jacobs Tel: +1 718 260-9447
