The "fast profile" is also known as "selector matching for rendering web pages". So the answer to your question is likely "probably not possible", unless you think web pages currently don't depend on this behavior. But worse yet, it's _faster_ to ignore uniqueness, no? It makes matching ids a completely local property, whereas any sort of uniqueness requirement makes id matching depend on global document state. > and an incentive for render-engines really use distinct algorithms for > each profile, Why is this a goal? Distinct algorithms suggests likely bugs in which the two profiles don't produce the same results in the same UA, which seems fairly suboptimal. -Boris
