[whatwg] RDFa is to structured data, like canvas is to bitmap and SVG is to vector

And I also said that we would have to address the issue of namespaces, 
which actually may require additional effort. I said that the addition 
of RDFa would mean the addition of some attributes, and we would have to 
deal with namespace issues. Just like the HTML5 working group is having 
to deal with namespaces with MathML and SVG. And probably the next dozen 
or so innovations that come along. That is the price for not having 
distributed extensibility.

One works the issues. I assume the same could be said of any many of the 
newer additions to HTML5. Are you then saying that this will be a 
showstopper, and there will never be either a workaround or compromise?
