No, that's just a different point. The discussion was about disaster warning - which needs an immediate reflex response. An iconic representation for imminent disaster can (and in fact must) be in multiple modalities simultaneously and needs to be pre-learned in order to be a reflex. Your point about using iconic systems is valid and useful, most of us use such systems every day - for example the international driving symbols. To be fluent in their use you also need to pre-learn them of course, and pictorial or rebus type systems definitely have their uses, both mainstream and as accessibility aids. The question is whether or how we should account for them in WCAG. Bliss is interesting, and there are other symbolic representations, for example of manual signing; the problem I have with these kinds of systems, is whether they are truly languages. If they are, then using them really comes under usability rather than accessibility - we don't talk about providing Hindi as an accessibility issue for example, however the Hindi speaking population of the UK is larger than the Deaf one, and it's a similar kind of problem if you only speak or read a minority language within a wider culture. If on the other hand there are some well defined uses of these kinds of symbols (such as fire EXIT), that would really make a difference, and which can be readily written up as specific techniques, then I think we should consider the use of such symbols as either primary, secondary or alternate modalities. It at least deserves a discussion.

I think a huge fundamental point is being missed thousands of people who have extremely limited vocabulary of traditional word can manage 1000's of symbol combinations. Universal symbolic languages exists and are in use (such as BLISS) so the whole "prior need for understanding of iconic representations" is already taken care of for many many people.

Exit signs in buildings, air-raid sirens, police sirens etc. are all instances of this. It's no good trying to work out what the message means when you receive it - the response has to be Pavlovian and immediate.

When it comes to web-based early Tsunami warning or other disaster warning system, accessibility and comprehension is crucial to protect the lives of readers of the web contents. Just think about it is streamed video contents with potentially dangerous area maps which is not legible with tiny mobile phone screen. Everybody requires either nonvisual alternatives or simplified graphics which is legible even on the small screen that is associated by exact language for instruction to the audiences in dangerous areas. The language part need to be as clear as possible, e. g. YOU MUST EVACUATE TO A PLACE HIGHER THAN 20 METERS FROM THE SEA LEVEL NOW! The sentence in capital letters above need to be understood clearly and immediately. A "power card" type web contents with synchronized audio and simple graphics will help everybody including persons with cognitive disabilities, in this use case, need to be accommodated by alternative graphical expression including symbols such as "emergency exit" or "tsunami evacuation route". This is applicable for Hurricane and other disasters, and of course cruicial for survival of individuals with disabilities including cognitive disabilities as well as people with different language and culture.
