JRG: I agree >Issue 2) The definition of "recognize" needs review. I don't have a >proposal > right now. JRG: Our use of recognize seems to also mean "interpret", if that helps with a definition >Issue 3) Define set of explicit submit controls for HTML > Checkpoint 11.2 reads: Allow configuration so the user is > prompted to confirm any form submission not caused by explicit > activation of a form submit control. > > Proposal: Add to the Note following the checkpoint that in HTML 4, > the only explicit controls are INPUT type="submit" and type="image", > and BUTTON type="submit". JRG: Yes I think this would help clarify the HTML 4 case. In the case of scripting though the user agent will also know that the script is requesting a new document using the "location" property (NN) or method with 3 types of methods (IE) of the windows object. In this case the user agent does not know if this function was called as part of an explicit user request or if the script is generating the page change without explicit user notification. The script writer currrently would need to design there code for only explicit user activiation. >Issue 4) Change percentage back to proportion. > Checkpoints 9.4 and 9.5 used to say "proportion" and now they > say "percentage". I propose that was return to "proportion".

JRG: Seems reasonable to me. >Issue 5) Definition of "stalled". Checkpoint 9.4 reads: > > 9.4 When transferring content (e.g., a document, image, audio, video, > etc.) indicate what percentage of the content has been >transferred > and whether the transfer has stalled. > > Issue: What is the definition of "stalled"?

JRG: The user agent will typically issue a dialog box warning or render a web page if access to the resource is not available. This would seem to suffice for me. >Issue 6) Does relative position of the viewport include horizontal >position? > > Proposal: Yes. In fact, the dimensions depend on the viewport. An >audio > viewport would not (I believe) have this issue since the output is >one > dimensional. JRG: I I think horizontal is very important for people with visual impairements. Many times they increase font size and information formatted in table columns disappears off the right hand side of the screen. Many users don't know the information is there and the horizontal scroll bars are important to give people information. >Issue 7) General advice about implementation of optional features of a > specification. > > Proposed: Add the following statement to the spec (as a Note to > either to checkpoint 6.1 or 6.2): > > "Developers should not implement an optional feature of > a specification if that feature may pose accessibility > problems and if the user cannot turn off the feature > in the user agent." JRG: It seems reasonable to me, but what test do we give developers to know if it will affect accessibility? Is there an example of an optional feature?
