Stan,

there is definitely an "Accept" http-header which all browser send and 
specifies the list of mime-types a browser accepts. This header does 
indicate, for example, whether a picture format is supported... Why not 
enrich the declaration of the support for mathml-content or openmath 
(with their respective mime-types) with "mime-type-attributes" which 
specify the set of supported symbols (or content-dictionaries) ?

Making it a language would require an extra http-header, or do I 
mistake ?

Now, there's an extra issue here: would a browser declare that it 
supports the mathml-content-of-maple ?? How would it know it ??

paul
