mix proposal

I am wondering about the following mix 1. A semi complex single attribute for context   <button aui="submit critical symbol(http://uri.html) step(5)" > These are all content descriptors. This allows more then one context descriptors from fixed vocabularies and symbols. The con is it is slower to parse, slower to process and some more author error as the vocabularies are not separated. I am not sure if it works with things like css selectors. 2. Then we have a clarification  value pair for free text for easy lang, litral etc. this could be like clarification="this costs less money" clarificationType="easylang numberfree"  If you do not fill in clarificationType the default is easylang. Note the aui- option is still easier to parse and will probebly have much better performance. this is a big issue for implementations   I suspect we should have tow option and go to web apps and people like James for their opinion.
