Does :remote=>true in Rails3 auto downgrade?
===

I have read about using `:remote=>true` in rails3 and know that it add `data-remote=true` attribute to the generated html tag. But `data-remote` is a new attribute introduced in html5. Will `:remote=true` auto downgrade to some compatible implementation(old js or something else) in a browser that doesn't support `data-remote` attribute?
