[Commentor] LC-305 Ian Jacobs [Comment] * I have a similar concern as above about "unless you know." I think that some of these checkpoints make more sense at certain points in a pipeline than at others. For instance, I as a human author probably don't know whether a particular user agent supports this or that. On the other hand, a piece of software that is actively involved in some protocol negotiation and that is doing content adaptation may very well have that information available. But the points are written for multiple audiences and therefore may be confusing. * What is "an available geometric shape"? I think you mean that the format supports the shape. [Working Group decision] The document is about delivered content. The inference for a content author is that if they specify an image map, then under certain circumstances this will not work so they should in addition consider an alternative linear arrangement of links. We have shortened the best practice to: "Do not use image maps unless you know the target client supports them effectively." and explained "effectively" in the text with the remainder of the BP as it is now put. We have also included a note to the effect that Image Maps on the Mobile Web are a bad idea. [Commentor reply]
