    The problem with any FPI that we come up with is that vendors may 
not implement all specifications, and if they don't, there's no way of 
knowing which they will support unless we make them dependent on earlier 
specs. So if we do different doctypes for all possibilities, we get the 
following situation:

"-//WHATWG//DTD HTML4 + WF2//EN"
"-//WHATWG//DTD HTML4 + WA1//EN"
"-//WHATWG//DTD HTML4 + WC1//EN"
"-//WHATWG//DTD HTML4 + WF2 + WA1//EN"
"-//WHATWG//DTD HTML4 + WF2 + WC1//EN"
"-//WHATWG//DTD HTML4 + WA1 + WC1//EN"
"-//WHATWG//DTD HTML5//EN"

    Now add revision numbering on top of that. Good luck.
