I don't see any rationale for making it mandatory, since there is no  
reason to suppose a priori that what makes a given canvas element  
accessible is the content of the element - it may very well be done  
outside the element content, while the internal content is used to provide  
fallback for user agents that don't support canvas (and users who have  
turned it off).

(The fact that both the current spec draft and the navsubtree proposal  
confuse these two uses of the element content, sometimes requiring that a  
conscientious author build a second version of the element content in  
javascript when that doesn't seem necessary, is the basis of why I don't  
like them).
