1) Why can't you use Microdata for both of those just as easily?

2) Why shouldn't these vendors be forced to go through the
standardization process like everyone else if they want documents
containing their feature to be valid HTML?  If the feature is not
openly specified, it will only work with some UAs, and arguably has a
higher chance of being poorly considered.  As soon as there's a formal
specification of a feature, and anyone wants to implement it, it's an
"applicable specification" and can simply add new attributes if it
