Re: SCR37 replacement

Hey Alastair,
I'm happy with this as an advisory technique. I think as a sufficient
technique this is confusing. The part of SC37 that made it directly
relevant to SC 2.4.3 was test 3 "Check that, once opened, the dialog is
next in the tab order.". In the rewrite, that part was replaced with a test
that is no longer about the order in which elements are in sequential focus
navigation. "When the dialog is opened, check that focus is placed inside
it.". I support that change. That is a better way to do this, but it
removed the only thing in SC37 that was about the order in which elements
appear when a user navigates the page with tab focus.
