What information is required? To discuss in a teleconf. ISSUE: What document summary information must the UA make available? Specific information should be the in the checkpoint, the rest in techniques. If no specific information is required, the checkpoint should be dropped and the topic discussed in the techniques document. > 6.1.11 [Priority 3] > Provide the user with information about document loading status > (e.g., whether loading has stalled, whether enough of the page has loaded > to begin navigating, whether following a link involves a fee, etc.) > > CMN: This is also very vague.

I agree that 6.1.9 and 6.1.11 should be combined and that the information required be specified more clearly. The last example about whether following a link involves a fee is related to the W3C ECommerce Activity, Micropayments WG. This sounds like a dependence with that group, i.e., that markup of a "fee link" must be recognizable in some way. PROPOSAL: - Drop the "fee link" part of the example - Talk to the Micropayment WG about this dependency. > 6.2 Provide information about document structure PROPOSAL FROM CMN for different checkpoints: > The checkpoints are, so far as I can see, as follows: > > 1.

This will be covered in the conformance section by the definition of "applicable checkpoint". >Should it apply to navigating the children of an element which > handles bubbled events? I suspect so. I'm not sure. That's why the checkpoint refers to "associated event handlers", which in HTML will mean "on*" attributes.
